Vice President Kamala Harris (D) cast three tie-breaking votes in the U.S. Senate related to the Inflation Reduction Act. On August 6, she cast a vote to proceed with debate on the bill, and on August 7 she cast votes to approve an amendment and to pass the bill.

During her tenure, Harris has also cast 20 tie-breaking votes related to confirmations and three related to the American Rescue Plan, bringing her total to 26.

Harris has cast the most tie-breaking votes in the Senate during a single vice presidential term in American history. Harris is followed by John Adams, who cast 20 tie-breaking votes during his first vice presidential term, and George M. Dallas, who cast 19 tie-breaking votes during his one term in office.

Accounting for a vice president’s full tenure, Harris has cast the third most tie-breaking votes. The most were cast by John C. Calhoun (31), and the second most by John Adams (29).

Among vice presidents who have held office since 1981, Harris is followed by Mike Pence (R) at 13 tie-breaking votes, Dick Cheney (R) at 8, and George H.W. Bush (R) at 7. 

Under Article I, Section 3, Clause 4 of the U.S. Constitution, the vice president of the United States also serves as the president of the Senate. In this capacity, he or she may cast the deciding vote when there is a tie in the Senate.
