Who can override the President’s veto? A clear guide

Quick answer: Who can override the President’s veto?

Short summary: overriding presidential veto

Congress can override a presidential veto when both the House of Representatives and the Senate repass the bill by a two-thirds vote of Members voting, with a quorum present; this authority is grounded in the Constitution and remains the controlling rule in 2026.

The process for a standard veto begins when the President returns a bill with objections within the ten-day period; Congress then follows roll-call procedures to record recorded votes for repassage.

A pocket veto is different: if Congress adjourns during the ten-day period and the President takes no action, the bill does not become law and cannot be overridden. For the constitutional text and chamber guidance, see the Constitution and chamber summaries.

Why this matters

Knowing how overriding presidential veto works helps citizens follow major legislative decisions and gives lawmakers a clear procedural target when they seek to repass a vetoed bill.

When override attempts occur, they can determine whether a measure becomes law despite presidential objections, so the mechanics affect both policy outcomes and civic accountability.

What the Constitution says about vetoes

Text of Article I, Section 7

The constitutional basis for the presidential veto and Congress’s override power is in Article I, Section 7 of the Constitution, which sets the return period and grants Congress the authority to reconsider bills the President objects to; see the Constitution transcription for the exact language and structure.

This constitutional text remains the controlling rule in 2026 and is the primary source for how timing and the override authority are interpreted in practice National Archives and see our guide to the Constitution online.

Why Congress has override power

The framers placed the veto and the override in Article I, Section 7 to balance executive review with legislative final authority, so Congress alone has the power to repass a bill over a presidential objection by meeting the specified voting threshold.

Those structural choices explain why the return period and the two-thirds requirement are treated as constitutional rules rather than mere chamber customs; chamber offices and constitutional commentators use the text as the baseline for procedural practice U.S. Senate on vetoes

How a regular veto is overridden: the step-by-step procedure

Timing for return and reconsideration

When the President returns a bill with objections, the Constitution generally gives the President ten days, excluding Sundays, to sign or return a bill; if returned, the originating chamber receives the objections and may proceed to reconsider the measure.

That ten-day window starts when the President receives the enrolled bill, and returning the bill with objections triggers the formal reconsideration process in the originating chamber National Archives

Chamber votes and roll-call procedures

After reconsideration, each chamber must repass the bill by a two-thirds vote of Members voting, with a quorum present; chambers normally record these votes by roll call so the totals are public and official. See how the House schedules and records votes.

House and Senate offices maintain rules for calling up a reconsideration and for recording roll-call votes, and these procedures determine how the vote is scheduled, how members are counted, and how the final tally is certified U.S. Senate on vetoes

Pocket vetoes: how they differ and when overrides are not possible

Definition of a pocket veto

A pocket veto occurs when the President takes no action on a bill and Congress adjourns during the ten-day period; under that condition, the bill does not become law and Congress cannot override the decision.

Because the Constitution ties the pocket veto to adjournment and the President’s inaction, the outcome depends on whether Congress is in a posture that prevents return of the bill; for core guidance see the constitutional text and chamber descriptions National Archives and the CRS brief on regular and pocket vetoes Regular Vetoes and Pocket Vetoes: In Brief.

Adjournment timing and legal effect

Determinations about whether an adjournment allows a pocket veto can be contested and often depend on how the chambers define their adjournment or recess in that specific session.

Chamber offices and constitutional analysts treat such questions carefully because adjournment rules affect whether Congress retains the opportunity to consider an override or whether the bill simply lapses U.S. Senate on vetoes

Votes, majorities, and the two-thirds threshold explained

Counting votes: two-thirds of those voting

This distinction matters because abstentions and absences lower the number of votes needed for two-thirds of those voting, and chambers rely on recorded roll-call procedures to confirm the precise totals Congress.gov veto resource

Quorum and abstentions

A quorum must be present for the vote to be valid; if a quorum is not present, the chamber cannot complete the override procedure until attendance meets the rule. Quorum rules and timing for calling the roll are set out in chamber rules and precedents.

Because abstentions remove a Member from the yes-or-no tally, they can change the arithmetic for reaching two-thirds of those voting; for final legal effect parties and observers use official roll-call records to confirm outcomes Congress.gov veto resource

Historical frequency: how often overrides succeed

Successful overrides are historically uncommon; only a small fraction of presidential vetoes have been overturned, so most vetoes either stand or are not subject to override when a pocket veto applies. For historical overviews and counts, see summaries by the Congressional Research Service and by legislative records and the Senate’s historical counts Vetoes, 1789 to Present.

Readers looking for comprehensive lists of overrides and attempts should consult official databases and trackers that compile roll-call records and votes across administrations Congressional Research Service

Public trackers such as GovTrack and the databases on Congress.gov collect roll-call totals and provide a practical way to survey override success across time; these tools are useful for both researchers and civic readers tracking a live override attempt.

Because frequency varies by era and depends on partisan alignments in each Congress, historical statements should be checked against the primary vote records for the period in question GovTrack veto tracker

Notable override examples and short case studies

There are several well-documented override cases that show how bipartisan coalitions or large majorities produced successful repassages; for details and roll-call totals, consult the official vote records and legislative resources.

Case studies highlight patterns: strong cross-party support or clear majority margins in both chambers make an override feasible, while narrow margins typically fall short without additional defections.

For full roll-call details of individual override cases, researchers and journalists should reference the Congress.gov record or the Senate’s veto summaries to read the precise vote tallies and member votes for each attempt Congress.gov veto resource

Strategic considerations for lawmakers trying to override a veto

Lawmakers aiming to override a veto must build a two-thirds majority in each chamber, which often requires persuading some members of the other party or securing unusually high turnout from their own party’s members.

Common procedural tactics include scheduling the reconsideration at a time of high attendance, pairing votes to offset absences, and public messaging to encourage members to be present for the roll call; these moves address both the arithmetic and the optics of an override attempt Congressional Research Service

How citizens can follow and respond to veto and override actions

Citizens can track roll-call votes and override attempts by using the databases on Congress.gov and public trackers like GovTrack, which publish official vote totals and member-level data for each recorded roll call.

Before a repassage vote, constituents who wish to contact Members should reference the pending bill number and the recorded objections so their correspondence is specific and factual; primary sources and roll-call records provide the needed details GovTrack veto tracker

Common mistakes and misconceptions about overriding vetoes

Counting errors

A frequent mistake is to assume two-thirds of full membership is required rather than two-thirds of those voting; that error can lead observers to misread whether an override succeeded based on headline tallies alone.

Always check the official roll-call total, because the denominator for two-thirds excludes abstentions and absences when a quorum is present Congress.gov veto resource

Misreading pocket vetoes

Another common confusion is treating a pocket veto like a regular veto; pocket vetoes cannot be overridden in the same way because adjournment interrupts Congress’s opportunity to receive returned objections.

Determining whether adjournment permits a pocket veto is often a technical question that depends on the timing and the chambers’ definitions of adjournment for that session U.S. Senate on vetoes

Procedural pitfalls and technical errors to watch for

Quorum failures

A failed quorum can stall an override attempt; if a chamber lacks the required number of Members present, it cannot proceed to a valid recorded vote and must address attendance before reconsideration.

Quorum and voting rules vary by chamber and by the procedural posture of the motion, so observers should consult chamber offices and CRS analyses for contested points about voting validity Congressional Research Service

Timing and adjournment disputes

Disputes about adjournment status affect whether the ten-day pocket veto rule applies; these disputes have technical and occasionally contested legal implications that require close reading of the constitutional clause and chamber precedents.

When timing or adjournment is in question, authoritative guidance from chamber clerks and CRS should be consulted to resolve how the rule applies in a particular case National Archives

Practical scenarios: what an override attempt looks like in current politics

A narrowly divided chamber

In a narrowly divided chamber, absences and a few defections can make the difference between success and failure; because the two-thirds threshold is of those voting, every presence and vote matters for the denominator and numerator.

In such cases, leaders may schedule the vote when attendance is highest and negotiate pairings to secure the needed yes votes; live roll-call counts on official sites let observers follow the final math Congress.gov veto resource

A bipartisan coalition

When an override succeeds, it often reflects a bipartisan coalition where members from both parties cross party lines; these coalitions can create the large margins needed in both chambers.

Observers can study past successful overrides by reading the roll-call records and noting which members crossed party lines, then compare that pattern to current alignments to assess feasibility GovTrack veto tracker

Glossary of key terms

Veto: The President’s formal refusal to sign a bill into law, with objections returned to Congress; for the primary text see the Constitution.

Override: Congress’s power to repass a vetoed bill by a two-thirds vote in each chamber, which makes the bill law despite the President’s objection.

Quorum: The minimum number of Members who must be present for the chamber to conduct business; quorum rules affect whether an override vote can proceed.

Pocket veto: A veto that occurs when the President takes no action on a bill and Congress adjourns during the ten-day period, preventing return and blocking an override.

Roll-call vote: A recorded vote in which each Member’s vote is entered into the public record; roll-call totals are the authoritative source for override outcomes.

Two-thirds: The required fraction of Members voting that must vote yes in each chamber to override a regular presidential veto.

Conclusion: what readers should take away

Bottom line: Congress can override a regular presidential veto only if each chamber repasses the vetoed bill by a two-thirds vote of Members voting, with a quorum present; pocket vetoes are treated differently because adjournment can block return and override.
