In 2017, Mike Pence cast six tie-breaking votes during his first year in office, the most for any vice president. He broke a tie with John Adams, William Wheeler, and Alben Barkley, who all cast four tie-breaking votes within their first year. This was also the most tie-breaking votes in any single year since 1872, when there were seven cast by Schuyler Colfax during the Grant administration. Pence tied Colfax's single-year record in 2018 when he cast seven tie-breaking votes and overall cast the most tie-breaking votes (13) of any vice president since Colfax's vice presidency (1869–1873).
