Congress does more than make laws. It also supervises and limits the exercise of power by the other branches of US government. This Oversight and relations with the presidency A-Level Politics revision page explains congressional oversight, the constitutional checks Congress can exercise, and why its relationship with the president changes according to factors such as party control, divided government and the political circumstances of a presidency. It builds on congressional constitutional powers and law-making, while preparing you for presidential limitations. Edexcel explicitly requires students to assess both congressional oversight and its institutional effectiveness.

Revision Notes 📚
Oversight and relations with the presidency A-Level Politics revision: specification focus
Edexcel places oversight alongside representation and legislation as one of the central functions of Congress.
The specification requires knowledge and understanding of:
factors influencing the relationship between Congress and the presidency
the checks Congress has on the other branches of government
the extent to which these checks are institutionally effective
This means you need to do more than list congressional powers. You need to explain whether Congress can use those powers effectively in practice.
What is congressional oversight?
Edexcel defines oversight as:
the ability of one branch of government to supervise the work of another.
For Congress, oversight is particularly important in its relationship with the president and executive branch.
The US Constitution separates legislative and executive power. The president is therefore not directly responsible to Congress in the same way that an executive operating through a fused legislature would be.
Instead, checks and balances allow Congress to constrain, scrutinise and sometimes prevent presidential action.
This connects directly to separation of powers and checks and balances.
Oversight versus checks and balances
The concepts overlap but are not identical.
Oversight refers specifically to one branch supervising the activity of another.
Checks and balances refers more broadly to the constitutional powers that allow each branch to restrict the others.
For example:
Congress controlling presidential funding is a constitutional check and can help Congress supervise executive activity.
Senate approval of presidential appointments limits the president's ability to appoint officials without legislative involvement.
Impeachment provides Congress with a mechanism for holding federal office-holders accountable.
💡 Exam point: If a question asks whether Congress holds the president to account, do not simply list every constitutional check. Explain how the congressional power actually produces presidential accountability. The 2025 examiner report identified failure to make this connection as a significant weakness.
Congress and the president: an interdependent relationship
Congress and the president are institutionally separate, but neither can always achieve major political objectives without the other.
For example:
presidents rely on Congress to introduce and pass legislation
Congress passes legislation, but the president can veto it
presidents require congressional approval for funding
formal treaties require Senate ratification
presidential appointments can require Senate approval
The relationship therefore combines co-operation and conflict.
A president may be politically powerful, but separation of powers prevents presidential control of Congress.
Likewise, Congress has extensive constitutional powers but cannot simply dictate presidential action in every area.
This tension is central to the debate over whether checks and balances produce effective limited government or political gridlock.
Congress's legislative check on the president
Congress controls the federal legislative process.
A president may have an electoral mandate and a political programme, but presidents do not possess direct legislative power over Congress.
Edexcel's 2025 mark scheme emphasises that presidents rely on members of Congress to introduce legislation because separation of powers prevents direct presidential control of Congress.
This gives Congress substantial leverage.
Congress may:
support a presidential legislative proposal
amend it
delay it
reject it
refuse to introduce it
Therefore, presidential success in domestic policy can depend heavily on congressional cooperation.
This builds directly on the congressional law-making process.
Why legislative control can be an effective check
Imagine a president makes a policy objective the central promise of their presidency.
The president cannot simply turn the proposal into an Act of Congress.
Instead:
members of Congress must introduce legislation
the legislation must survive the congressional process
both chambers must agree
sufficient political support must be maintained
Congress can therefore limit presidential power simply by withholding legislative support.
This is one reason presidential powers of negotiation and persuasion matter, explored further in presidential persuasion.
The presidential veto
The legislative relationship also works in the opposite direction.
The president may veto congressional legislation.
This means the executive can check the legislature even after legislation has passed both chambers.
However, the presidential veto is not absolute.
Congressional veto override
Congress can override a presidential veto with a two-thirds majority in both the House of Representatives and Senate.
The 2025 Edexcel mark scheme identifies this as evidence that Congress can hold presidential power in check.
The relationship is therefore balanced:
Congress passes legislation → president may veto → Congress may override the veto
However, the two-thirds requirement makes an override significantly more difficult than ordinary passage of legislation.
This illustrates a recurring feature of Congress-presidency relations:
Congress often possesses a powerful constitutional check, but successfully using it may depend on having sufficient political support.
The power of the purse
Congress also controls government finance.
This is commonly described as the power of the purse.
The 2025 Edexcel mark scheme emphasises that presidents must obtain congressional approval for funding for executive programmes and cannot simply overrule Congress to obtain the money required.
This can be a particularly important congressional check because political ambitions normally require financial resources.
The basic relationship is:
presidential proposal → funding required → congressional approval needed
If Congress refuses the necessary funding, the president's ability to implement a programme may be substantially restricted.
Why the power of the purse matters
A president may possess other constitutional or informal powers, but those powers do not remove Congress's role in allocating federal funds.
This means Congress can constrain presidential activity by controlling resources.
Edexcel's 2022 examiner report highlighted the power of the purse as an important counterweight to presidential dominance, particularly in foreign policy discussions.
This is a good example of how to develop analysis:
Congress's financial powers are significant because presidential authority can be politically impressive but practically limited if Congress refuses to provide the resources required to implement executive policy.
Impeachment
Congress also possesses the constitutional power of impeachment.
As covered in the distribution of congressional powers:
the House of Representatives brings impeachment charges
the Senate conducts the impeachment trial
Impeachment therefore gives Congress a particularly serious means of holding federal office-holders, including presidents, accountable.
Is impeachment an effective check?
There are two ways to evaluate this.
Argument that impeachment is effective
The existence of impeachment means a president is not completely immune from congressional accountability.
Congress has a constitutional procedure for responding to serious presidential misconduct.
The 2025 Edexcel mark scheme notes that the fact Congress has used impeachment procedures can itself be interpreted as evidence that Congress is willing to exercise this check.
Argument that impeachment is limited
Attempts to use impeachment against presidents have not automatically resulted in removal from office.
Therefore, the existence of the power does not guarantee that Congress can successfully remove or constrain a president.
Its effectiveness can depend heavily on political circumstances and whether sufficient congressional support exists.
This demonstrates a key analytical distinction:
possession of a constitutional power does not automatically mean effective use of that power.
Senate approval of appointments
The Senate also checks the president through its role in appointments.
Important presidential nominations require Senate approval.
This may include appointments to the executive and judiciary.
The president therefore has the power to nominate, but cannot always determine appointments alone.
This creates a direct constitutional relationship:
presidential nomination + Senate approval
The Senate can therefore constrain presidential influence over government appointments.
This becomes particularly important when studying Supreme Court appointments.
Checking the judicial branch through appointments
The Senate's confirmation role also gives Congress influence over the composition of the federal judiciary.
Presidents nominate Supreme Court justices, but Senate approval is required.
This gives the legislative branch a constitutional role in the process by which the judicial branch is staffed.
However, once Supreme Court justices are appointed, judicial independence substantially limits continued congressional or presidential influence over how they decide cases.
Therefore, congressional influence is strongest at the appointment stage, rather than as continuing control of judicial decision-making.
Congress and treaties
Foreign policy illustrates particularly clearly the tension between presidential and congressional power.
The president can conduct important aspects of foreign relations, but formal treaties require ratification by a two-thirds majority of the Senate.
The 2025 Edexcel mark scheme explicitly identifies treaty ratification as a congressional means of holding presidential power in check.
This gives the Senate the ability to prevent a treaty from taking effect through the formal constitutional process.
Executive agreements as a limitation on congressional influence
Presidents can also make executive agreements.
The 2025 mark scheme identifies these as a potential weakness in congressional accountability because they can be made without initial congressional approval.
This illustrates how presidents can sometimes exercise foreign-policy authority without using procedures that give Congress a direct veto.
Therefore:
formal treaties demonstrate congressional checking power
executive agreements demonstrate a potential presidential route around that check
Congress and presidential foreign-policy power
The Constitution divides foreign-policy responsibilities.
Congress possesses important powers, but presidents also hold the constitutional role of Commander-in-Chief.
The 2025 mark scheme identifies presidential use of Commander-in-Chief powers, including the ability to act proactively in the deployment of troops, as one reason congressional checks may sometimes be limited.
This creates a tension:
Congress possesses constitutional authority in foreign policy, but presidents may have significant scope for immediate executive action.
This is developed further in constitutional presidential authority.
Executive orders and congressional oversight
Presidents may issue executive orders, official executive documents with the force of law directing federal officials to take particular actions.
The Edexcel specification includes executive orders as an informal source of presidential power.
Executive orders can complicate Congress-presidency relations.
If Congress refuses to support a presidential policy through legislation, a president may sometimes seek to act through executive authority instead.
The 2025 mark scheme identifies this as a reason Congress may fail to hold presidential power fully to account.
⚠️ However, Congress does not simply possess a power to cancel an executive order.
The 2022 examiner report identified the claim that Congress can simply revoke executive orders as a factual error.
Why Congress-presidency relations vary
The Constitution provides the basic institutional framework, but the actual balance of power changes.
The specification requires students to understand why relationships between Congress and the president vary. The related Presidency content identifies:
Congress
the Constitution
the election cycle
divided government
as important limitations on presidential power.
For Congress, the most important factors include party control, partisanship, elections and presidential powers of persuasion.
Divided government
Edexcel defines divided government as a situation where the House, Senate and presidency are not all controlled by one party.
Under divided government, Congress may be more willing to challenge the president.
The 2025 mark scheme states that congressional oversight may become stronger during divided government because presidents cannot rely as easily on members of their own party and may need to use persuasion to secure legislation or funding.
Possible consequences include:
greater congressional scrutiny
more opposition to presidential legislation
greater difficulty securing funding
more conflict over appointments or other presidential actions
However, divided government can also contribute to gridlock.
Therefore, stronger congressional checking does not necessarily mean more effective government.
Unified government
The presidency specification defines unified government as a situation where both houses of Congress and the presidency are controlled by the same political party.
Unified government can make Congress-presidency relations more cooperative.
Members of Congress may be more willing to:
introduce presidential proposals
support the president's legislative agenda
approve presidential priorities
The 2025 mark scheme suggests that under unified government Congress may sometimes scrutinise presidential proposals less aggressively because members of the president's party control the legislature.
This may increase presidential effectiveness but weaken congressional independence as a check.
Divided and unified government compared
Political situation | Likely effect on Congress-presidency relations | Possible consequence |
Divided government | Greater conflict between president and at least part of Congress | Stronger oversight, but greater risk of gridlock |
Unified government | Greater likelihood of cooperation | Easier policy-making, but potentially weaker scrutiny |
Narrow congressional majorities | Individual members or small groups become more significant | Presidential success can become unpredictable |
Strong partisanship | Members prioritise party loyalty | Oversight may depend heavily on whether the president shares their party |
The important point is that constitutional powers remain the same, but willingness and ability to use them change.
Partisanship
Edexcel defines partisanship as extremely strong loyalty to a political party, even where this results in gridlock.
Partisanship affects oversight because congressional attitudes towards the president may depend partly on party affiliation.
If the president's party controls Congress, members may be less willing to challenge a president from their own party.
If the opposition party controls a chamber, congressional resistance may become stronger.
The 2023 mark scheme identifies party control as an important reason checks and balances may vary in effectiveness.
The election cycle
Members of Congress are elected separately from the president.
House members face election every two years, while senators serve six-year terms.
This can affect presidential relations because legislators must consider their own electoral interests rather than simply follow the president.
As explored in congressional electoral pressures, members may respond to:
constituency opinion
party pressure
campaign considerations
their prospects of re-election
The president therefore cannot assume automatic loyalty from members of their own party.
Presidential powers of persuasion
Presidents also possess informal political resources.
Edexcel defines the power of persuasion as the use of presidential prestige and bargaining to encourage others to act as the president wishes.
This is necessary precisely because the president cannot formally command members of Congress.
A successful president may persuade legislators to support:
presidential legislation
funding requests
appointments
other policy objectives
Therefore, congressional independence does not mean presidential influence is absent.
The balance can depend on the president's political position and ability to persuade.
Presidential veto power
The veto can also affect Congress-presidency relations before it is actually used.
Members of Congress know that legislation opposed by the president may be vetoed.
This may encourage negotiation and compromise before final passage.
However, Congress retains the constitutional power to override a veto with a two-thirds vote in both chambers.
The relationship is therefore not one of presidential control, but mutual constitutional constraint.
Congress's checks on the executive: summary
Congressional power | How it checks the president | Main limitation |
Legislative power | Congress can refuse, amend or delay presidential legislative proposals | President may use persuasion or other executive powers |
Power of the purse | Congress controls funding for presidential programmes | Political majorities may support presidential spending |
Veto override | Congress can defeat a presidential veto with two-thirds support in both chambers | Supermajority is difficult to achieve |
Impeachment | Congress can formally hold a president accountable | Successful removal requires substantial political support |
Appointment approval | Senate can reject presidential nominations | Unified government may make confirmation easier |
Treaty ratification | Senate can refuse formal treaty ratification | Presidents may make executive agreements |
General oversight | Congress can use its constitutional powers to supervise executive activity | Effectiveness varies according to political context |
Checking the Supreme Court
The specification does not restrict congressional checks to the president. It refers to checks on the other branches of government.
Congress therefore also has a relationship with the judiciary.
Two important connections already studied are:
Senate confirmation of Supreme Court nominees
congressional impeachment powers over federal office-holders
The Senate appointment role means Supreme Court membership cannot be determined by the president alone.
However, congressional checking power over judges is limited by the constitutional independence of the Court once justices are appointed.
The wider question of judicial independence is explored in the constitutional role of the Court.
Is Congress institutionally effective?
Institutional effectiveness asks whether Congress can actually use its constitutional position to limit other branches.
There are strong arguments on both sides.
Argument that Congress is an effective check
Congress controls legislation
Presidents rely on Congress for major legislation.
Congress can refuse to pass presidential proposals.
This means the executive cannot routinely dominate domestic law-making.
Congress controls money
Congressional control of funding can significantly constrain presidential programmes.
A president cannot simply order Congress to supply resources.
Congress participates in appointments
Senate confirmation prevents presidents from exercising complete control over major appointments.
Congress controls treaty ratification
Formal treaties require substantial Senate support.
Congress can override presidential vetoes
The president cannot exercise an absolute legislative veto.
Congress can use impeachment
The Constitution provides a mechanism for holding presidents and other federal officials accountable.
Together, these powers make Congress potentially a very substantial constitutional check.
Argument that congressional checking is limited
Presidential executive action
Executive orders and executive agreements may allow presidents to act without first obtaining congressional approval.
Commander-in-Chief powers
Presidents may exercise significant freedom in foreign affairs, making congressional control less immediate.
Unified government
Members of Congress may be less willing to challenge a president from their own party.
Supermajorities are difficult
Some of Congress's strongest checks require unusually high levels of support.
For example:
veto override requires two-thirds in both chambers
treaty ratification requires two-thirds of the Senate
A constitutional power can therefore exist without being easily usable.
Partisanship affects willingness
Oversight may become shaped by party loyalty rather than simply constitutional principle.
The strength of Congress may therefore depend as much on whether legislators want to exercise their powers as on whether those powers exist.
Constitutional power versus political willingness
This is one of the most important ideas in this topic.
Congress may possess a constitutional check but choose not to use it aggressively.
Equally, Congress may try to use a constitutional power but lack sufficient votes.
Therefore:
constitutional capacity + political willingness + sufficient congressional support = effective oversight
If any one of these is missing, oversight may be weaker.
The 2025 examiner report specifically praised top-level responses that considered Congress's willingness to use its oversight powers, alongside the continued existence of presidential powers and the political composition of Congress.
Does stronger oversight mean more effective government?
Not necessarily.
Effective checking may restrain excessive presidential power, but conflict between Congress and the presidency can also produce gridlock.
Edexcel defines gridlock as a situation in which Congress and the president repeatedly prevent each other from acting, making legislation difficult to pass.
This creates an important evaluative tension:
Strong checks can protect limited government, but they can also obstruct effective government.
The 2023 Edexcel mark scheme recognises both sides. Checks and balances can prevent one branch becoming too powerful, but their complexity can also leave government unable to reach consensus.
How context changes congressional power
Congress's formal powers are constitutional, but their practical importance changes over time.
The 2022 examiner report praised responses that recognised presidential power could "ebb and flow" according to circumstances and that analysed factors such as:
political climate
presidential term
divided government
partisanship
This is a valuable model for your own analysis.
Instead of writing:
Congress has the power of the purse, so Congress is powerful.
Write:
The power of the purse gives Congress a significant constitutional check because presidential programmes may depend on congressional funding. However, its effectiveness varies according to political circumstances, since a Congress controlled by the president's party may be more willing to approve executive spending priorities.
That moves from AO1 knowledge to AO2 analysis and AO3 evaluation.
Preparing for wider debates about Congress
This lesson leads directly into the overall effectiveness of congressional power.
At that stage, you need to consider whether Congress's constitutional powers remain significant in practice and whether changes in parties, representation and inter-branch relations have altered the institution's importance.
It also overlaps closely with presidential limits and institutional relationships, where the same relationship is considered from the perspective of presidential power.
Hints from the Examiner Reports 💡
Examiner hint: A question about holding the president to account is not simply a general question about checks and balances. The 2025 examiner report found that candidates sometimes described appointment powers without explaining how they demonstrated presidential accountability. Always connect the constitutional power directly to the question.
Examiner hint: Organise 30-mark answers around clear themes such as impeachment, legislation, domestic policy or foreign policy. The strongest 2025 responses selected a theme, analysed how Congress could hold the president to account within that theme and then evaluated how effective that particular mechanism was.
Examiner hint: Evaluate the point you have just made. Some 2025 candidates explained why impeachment was limited and then switched to the power of the purse as their "evaluation". Examiners noted that this does not fully evaluate the original argument. Instead, assess the strength and weakness of impeachment itself before moving on.
Examiner hint: Do not drift into an essay about the Supreme Court, presidential elections or the imperial presidency unless the material is explicitly connected to Congress's ability to hold the president accountable. Irrelevant political knowledge does not gain credit.
Examiner hint: Move beyond listing powers. The 2025 report stressed that candidates need to explain the significance of congressional methods and reach developed conclusions about how effective they actually are.
Examiner hint: The 2023 examiner report found that weaker candidates sometimes assumed a check must be effective simply because it exists. Stronger responses explained the limits affecting each check and used this to judge its effectiveness.
Common Mistakes ⚠️
Mistake: Treating oversight as simply another word for law-making
Why this is incorrect: Oversight is the ability of one branch to supervise another. Congress's legislative powers can contribute to oversight, but congressional oversight is broader than simply passing laws.
How to improve: For each power, explain how it allows Congress to supervise, limit or hold another branch accountable.
Mistake: Assuming the existence of a check proves it is effective
Why this is incorrect: A veto override, impeachment or treaty power may exist constitutionally but still be difficult to use successfully.
How to improve: Ask two questions every time: What power does Congress possess? What could prevent Congress from using it effectively?
Mistake: Saying Congress can veto a presidential veto
Why this is incorrect: Congress does not "veto the veto". It may override a presidential veto with a two-thirds majority in both chambers.
How to improve: Use the correct phrase veto override.
Mistake: Saying Congress can simply revoke an executive order
Why this is incorrect: The 2022 examiner report specifically identified this as a factual error.
How to improve: Treat executive orders as a potential limitation on congressional influence, not as presidential legislation that Congress can simply cancel.
Mistake: Assuming divided government makes Congress weak
Why this is incorrect: Divided government can actually make congressional oversight of the president stronger because members of the opposition party may be more willing to resist executive proposals.
How to improve: Distinguish oversight effectiveness from government effectiveness. Stronger oversight may also produce more gridlock.
Mistake: Assuming unified government removes separation of powers
Why this is incorrect: The constitutional branches remain separate regardless of party control.
How to improve: Say unified government may make Congress less willing to use its checks aggressively, rather than claiming the checks cease to exist.
Mistake: Turning an accountability question into a list of presidential powers
Why this is incorrect: Knowing that presidents can issue executive orders or act as Commander-in-Chief is only useful if you explain how this affects Congress's ability to supervise or restrain them.
How to improve: Use the chain:
presidential power → congressional response → limitation on that response → judgement about accountability.

Answer:
Any two appropriate examples, such as:
control of legislation
control of funding
impeachment
Senate approval of appointments
Senate treaty ratification
overriding a presidential veto
Award 1 mark for each correct power.
Question 3
Explain two ways in which divided government may affect relations between Congress and the president. (4 marks)
reveal mark scheme and indicative content
Indicative mark scheme:
Award up to 2 marks for each developed point.
Relevant points include:
Members of an opposition-controlled chamber may be more willing to scrutinise and oppose presidential proposals.
The president may find it harder to obtain approval for legislation or funding.
Greater inter-branch conflict may increase the likelihood of gridlock.
Presidents may become more dependent on persuasion and negotiation with Congress.
Question 4
Explain how the power of the purse can be used to check presidential power. (4 marks)
reveal mark scheme and indicative content
Indicative mark scheme:
Relevant points include:
Presidents require congressional approval for funding of executive programmes.
Congress may refuse or restrict the money needed for presidential proposals.
The president cannot simply overrule Congress to obtain the required funding.
Financial control can therefore limit what the executive is practically able to achieve.
Question 5
A president proposes a major policy reform. The opposition party controls one chamber of Congress and refuses both to pass the proposed legislation and to provide the funding required.
Analyse why this represents a significant congressional check on presidential power. (6 marks)
reveal mark scheme and indicative content
Indicative mark scheme:
Relevant points include:
Separation of powers means the president cannot directly pass legislation.
Congressional support is required for the proposal to become federal law.
Congress also controls funding.
Opposition control of a chamber may make legislators more willing to challenge the president.
The president may therefore have to negotiate or use powers of persuasion.
This demonstrates how divided government can strengthen congressional oversight while potentially causing gridlock.
Question 6
A president negotiates an international agreement and wants it to take effect as a formal treaty.
Explain how Congress may check the president in this situation and assess one limitation on this congressional power. (6 marks)
reveal mark scheme and indicative content
Indicative mark scheme:
Relevant points include:
Formal treaties require ratification by a two-thirds majority in the Senate.
The Senate can therefore prevent a presidential treaty from completing the constitutional process.
This checks presidential foreign-policy power.
However, presidents can also use executive agreements that do not require congressional approval in the same way.
Presidential foreign-policy authority may therefore reduce the overall effectiveness of congressional control.
Question 7
Analyse why Congress may be more effective in checking the president during divided government than during unified government. (12 marks)
reveal mark scheme and indicative content
Indicative mark scheme:
Strong responses could develop several themes.
Party control:
Under divided government, at least one congressional institution is not controlled by the president's party.
Opposition members may therefore have a stronger political incentive to scrutinise executive actions.
During unified government, members of the president's party may be more willing to support the presidential programme.
Legislation and finance:
An opposition-controlled Congress can refuse legislation or funding.
Presidents therefore become more dependent on negotiation and persuasion.
During unified government, presidential proposals may encounter less resistance.
Limits to the argument:
Congress remains constitutionally separate under unified government and can still reject presidential proposals.
Members have their own constituencies and electoral interests.
Divided government may produce gridlock rather than constructive oversight.
Strong congressional checking does not necessarily mean more effective policy-making.
Higher-level answers should distinguish Congress's constitutional capacity to check the president from its political willingness to use those checks.
Question 8
Evaluate the view that Congress is ineffective at holding the president to account.
reveal mark scheme and indicative content
You must consider this view and the alternative to this view in a balanced way. (30 marks)
Indicative mark scheme:
Arguments supporting the view
Impeachment may be difficult to use effectively
Congress possesses the constitutional power, but impeachment does not guarantee removal.
Political support can determine whether the process successfully restrains a president.
Executive orders
Presidents may use executive powers where congressional agreement cannot be reached.
This may reduce Congress's immediate ability to control policy.
Unified government
Congress may be less willing to challenge a president from the same party.
Party loyalty can weaken scrutiny.
Commander-in-Chief role
Presidents may exercise significant initiative in foreign policy.
Congressional checking may therefore be less immediate.
Executive agreements
Presidents may make agreements without using the formal treaty process requiring Senate ratification.
Arguments challenging the view
Legislative control
Presidents depend on Congress to turn major policy proposals into legislation.
Congress can refuse to introduce or pass a presidential programme.
Power of the purse
Congress controls federal funding.
Presidential programmes may therefore be impossible without congressional approval.
Veto override
Congress can override a presidential veto with a two-thirds majority in both chambers.
Divided government
Congressional scrutiny may become significantly stronger when the opposition controls part of Congress.
Treaty ratification
Formal treaties require a two-thirds Senate majority.
Appointments and impeachment
Congress has important constitutional powers capable of constraining the executive and influencing appointments.
Judgement
A strong judgement should avoid arguing that Congress is either permanently powerful or permanently weak.
Congress possesses extensive constitutional powers to supervise and constrain the president, meaning the institution is potentially a very strong check. However, the effectiveness of those powers depends heavily on political circumstances.
The most important distinction is therefore between formal power and practical effectiveness. Divided government, sufficient congressional majorities and a willingness to challenge the executive can make oversight powerful. Unified government, partisanship, supermajority requirements and independent presidential powers can make the same constitutional checks far less effective.
The strongest overall judgement is likely to conclude that Congress's ability to hold the president accountable varies according to political context rather than because its constitutional powers fundamentally change.
