Vice President Kamala Harris has tied the record for tie-breaking votes in the Senate that was set nearly 191 years ago by John C. Calhoun.

Harris on Wednesday voted in favor of ending debate on the nomination of Kalpana Kotagal to be a member of the Equal Employment Opportunity Commission, her 31st tie-breaker vote since entering office with President Joe Biden two and a half years ago.

“This is a history-making moment for the United States Senate,” Majority Leader Charles E. Schumer said after the motion was agreed to on a 51-50 vote. “When it’s mattered most, Vice President Harris has provided the decisive vote on some of the most historic bills of modern times … to so many federal judges who now preside and provide balance on the federal bench.”

With two years of a 50-50 Senate, Harris’ tie-breaking ability proved especially crucial for Democrats in getting their priority legislation passed, including COVID-19 relief measures and their fiscal 2022 reconciliation package. While Democrats have taken a very slight 51-49 majority, her vote has been necessary to confirm controversial Biden nominees through attendance issues and Democratic no votes.
