Vice President-elect Kamala Harris submitted her resignation from her seat in the U.S. Senate on Jan. 18, two days before Inauguration Day.
“As I resign from the Senate, I am preparing to take an oath that would have me preside over it,” Harris wrote in her resignation letter. “As senator-turned-Vice-President Walter Mondale once pointed out, the vice presidency is the only office in our government that ‘belongs to both the executive branch and the legislative branch.’ A responsibility made greater with an equal number of Democrats and Republicans in the Senate.”
