Presidential Vetoes, 1789-Present:
A Summary Overview

Summary
The veto power vested in the President by Article I, Section 7 of the Constitution
has proved to be an effective tool for the Chief Executive in his dealings with Congress.
Since the beginning of the federal government in 1789, 35 of 42 Presidents have
exercised their veto authority 2,549 times. Of that total number, 1,484 have been
returned vetoes—i.e., the rejected legislation was returned to the congressional house
of origin, while it was in session, with a presidential message of explanation—and 1,065
were pocket vetoed or rejected while Congress was adjourned. Congress has challenged
the President's veto 313 times and succeeded in overriding on 106 occasions.
How Vetoes Work
After legislation has been approved by both houses of Congress and presented to the
President, he may sign it into law within the 10-day period prescribed in the Constitution,
let it become law without his signature, or veto it. To become law, congressionally
approved bills and joint resolutions, except those proposing amendments to the
Constitution, must be presented to the President for final action. Amendments to the
Constitution, which require a two-thirds vote in each house, are sent directly to the states
for approval. If Congress is in session when the President exercises his veto authority, the
disapproved bill is returned to the house where it originated along with a presidential
message explaining the reasons for its rejection. To sustain a veto, the President needs the
vote of only one more than one-third of a quorum in either the House of Representatives
or the Senate.1
1 A quorum is defined as the number of members whose presence is necessary for the transaction
of business. In the Senate and House, it is a majority of the membership (when there are no
vacancies, this is 51 in the Senate and 218 in the House). A quorum is 100 in the Committee of
the Whole House.

If Congress has adjourned, preventing the return of a bill, the President may withhold
his signature beyond the constitutionally prescribed 10-day action period and the bill
neither becomes law nor is returned to Congress for further action. This practice has been
dubbed a "pocket veto." Unlike the situation when a vetoed bill is returned to a house in
session, Congress does not have an opportunity or constitutional authority to override a
pocket veto.
Congressional procedure for reconsidering vetoed legislation is similar in both the
House and the Senate. Congressional action on a vetoed measure begins when the
President returns the bill to the house of origin along with a veto message indicating his
objections. Once the vetoed legislation has been received, the originating chamber is
constitutionally required "to reconsider" the vetoed bill. The Constitution is silent,
however, on the definition of "reconsideration." In lieu of constitutional direction, House
and Senate procedures and tradition govern the treatment of vetoed bills returned by the
President. Upon receiving a vetoed bill, the President's message is read into the journal
of the house to which it was directed, and the constitutional requirement "to reconsider"
is realized by laying the measure on the table, referring the bill back to committee,
postponing consideration to a certain day, or immediately voting to override.
