Who is the Vice President of the United States?

The Vice President of the United States is Kamala Harris. She made history by becoming the first female vice president and the first woman of Black and South Asian descent to hold this office. This role includes serving as the President of the Senate, where she can cast a tie-breaking vote, and assisting the President in various duties.

The other individuals listed, while prominent political figures, do not currently hold the position of Vice President. Sarah Palin was the 2008 Republican vice-presidential nominee, Kirsten Gillibrand is a sitting U.S. Senator from New York, and Elizabeth Warren is also a U.S. Senator representing Massachusetts. Their notable contributions to politics do not include holding the vice presidency, which underscores the significance of Kamala Harris's role in current U.S. governance.
