What Is the Presidential Veto? Pocket Veto, Overrides, and Limits Explained
The presidential veto is a constitutional check on Congress. A president can reject legislation with a single signature — or no sigfont-size:1rem;max-width:640px;margin:0 0 8px;"> The presidential veto is a constitutional check on Congress. A president can reject legislation with a single signature — or no signature at all — and overriding a veto requires a two-thirds supermajority in both chambers.
- Overriding a veto requires two-thirds of both chambers — 290 House + 67 Senate; fewer than 5% of all presidential vetoes in US history have been overridden
- A pocket veto occurs when Congress adjourns within 10 days of sending a bill to the president — the bill dies automatically and cannot be overridden, because there is no Congress in session to attempt one
- Under unified government (same party controls Congress and White House), vetoes are rare — the president and Congress mostly agree; vetoes most often occur under divided government
- The Supreme Court struck down the Line Item Veto in Clinton v. New York (1998) — the president cannot selectively cancel individual spending items in a law; the full bill must be signed or rejected
The Constitutional Basis for the Veto
The veto power is established in Article I, Section 7 of the Constitution, known as the Presentment Clause. Every bill passed by both chambers of Congress must be presented to the president, who has three options: sign it into law, veto it (return it to Congress with objections), or take no action for 10 days.
If the president takes no action for 10 days and Congress is in session, the bill becomes law without the president's signature. If Congress adjourns within those 10 days and the president takes no action, the bill does not become law — this is the pocket veto, which cannot be overridden because there is no Congress to return the bill to.
The veto was one of the most debated provisions at the Constitutional Convention. Some delegates wanted an absolute veto; others wanted none at all. The two-thirds override requirement was the compromise — the president gets a meaningful check, but a broad enough congressional coalition can still override it.
Types of Vetoes
Regular (Return) Veto
The president returns the bill to Congress within 10 days with a written veto message explaining the objections. Congress can then attempt to override with a two-thirds vote in each chamber. If the override fails in either chamber, the veto stands and the bill dies.
Pocket Veto
If Congress adjourns within 10 days of presenting a bill and the president does not sign it, the bill dies silently. No override is possible. Presidents have used the pocket veto strategically to kill legislation without issuing a formal veto message. Presidents have vetoed over 1,000 bills via pocket veto throughout US history.
Signing Without Approval
A president may sign a bill into law while issuing a signing statement expressing disagreement with specific provisions. Signing statements do not have the force of law but can signal how the executive branch intends to interpret and implement the legislation. Presidents have issued thousands of signing statements, and their legal significance is disputed.
Line Item Veto (Struck Down)
Congress passed the Line Item Veto Act in 1996, giving President Clinton the power to cancel specific spending items in appropriations bills. The Supreme Court struck it down in Clinton v. City of New York (1998), ruling that it violated the Presentment Clause because it allowed the president to unilaterally amend legislation after enactment. Restoring a constitutional line-item veto would require a constitutional amendment.
Veto Override: How Rare Is It?
Veto overrides are rare in modern American politics because party cohesion makes it nearly impossible to assemble two-thirds of both chambers against a president of your own party's opposition. As long as the president retains roughly one-third of either chamber, the veto will hold.
Historical overrides have been most common when a president becomes politically isolated. Andrew Johnson had 15 vetoes overridden by the Reconstruction Congress. Franklin Pierce had 9 overridden. In the modern era, the most recent significant override was in January 2021, when both chambers overrode Trump's veto of the National Defense Authorization Act — Republicans joined Democrats in the Senate 81-13.
Some presidents have almost never been overridden: FDR issued 635 vetoes (a record) and was overridden only 9 times. Presidents who work closely with their congressional majority rarely face credible override attempts, as the veto threat itself can shape legislation before it reaches the president's desk.
| President | Total Vetoes | Pocket Vetoes | Overrides | Notable |
|---|---|---|---|---|
| FDR (1933–45) | 635 | 263 | 9 | All-time record; managed large New Deal legislative majority |
| Truman (1945–53) | 250 | 70 | 12 | Most overrides in modern era; Taft-Hartley Act override attempt failed (1947) |
| Eisenhower (1953–61) | 181 | 108 | 2 | Used pocket veto extensively; worked with Democratic Congress |
| Reagan (1981–89) | 78 | 39 | 9 | Civil Rights Restoration Act overridden (1988) |
| Clinton (1993–01) | 37 | 1 | 2 | Signed Line Item Veto Act (1996); struck down by SCOTUS (1998) |
| Bush W. (2001–09) | 12 | 0 | 4 | Fewest vetoes first term (unified govt); stem cell, CHIP bills vetoed |
| Obama (2009–17) | 12 | 0 | 1 | JASTA override (9/11 Saudi Arabia suit) — only override of his presidency |
| Trump (2017–21) | 10 | 0 | 1 | NDAA 2021 overridden 81–13 Senate; last successful congressional override |
| Biden (2021–25) | 22 | 0 | 0 | War Powers resolutions, immigration, financial regulation; no overrides |
Frequently Asked Questions
Which president issued the most vetoes?
Franklin D. Roosevelt issued 635 vetoes over his four terms (1933-1945), the most of any president. Grover Cleveland is second with 584 total vetoes across two non-consecutive terms. FDR's record reflects both his long tenure and his active management of New Deal legislation. Modern presidents issue fewer vetoes, in part because they work more closely with their congressional majorities to shape bills before they reach the White House.
Can the president veto individual provisions of a bill?
No. The Supreme Court's ruling in Clinton v. City of New York (1998) established that the president must sign or veto an entire bill. The Presentment Clause requires the same bill that passed Congress to be signed into law; altering it afterward is unconstitutional. This is why Congress sometimes uses omnibus bills to bundle unpopular provisions with must-pass legislation — knowing the president cannot selectively veto only the unwanted parts.
Can the Senate filibuster an attempt to override a veto?
No. Veto override votes in the Senate proceed under constitutional rules and cannot be filibustered. The Constitution specifies that the two-thirds override vote shall proceed without possibility of delay through normal parliamentary obstruction. However, the Senate leadership controls scheduling and can simply decline to bring a veto override vote to the floor, which has the same practical effect as blocking it without technically obstructing the vote itself.
