Who is the current Vice President of the United States?

The current Vice President of the United States is Kamala Harris. She made history by being the first female Vice President, the first Black Vice President, and the first person of South Asian descent to hold the office. Her role includes assisting the President, presiding over the Senate, and representing the U.S. in various functions both domestically and internationally. This answer reflects the most recent historical context and positions held in Washington, D.C.

The other names provided are associated with different roles or positions in government but do not fulfill the duties of the Vice Presidency as currently held by Kamala Harris. James David (JD) Vance is a U.S. Senator from Ohio, Mike Pence served as the previous Vice President under Donald Trump, and John Roberts is the Chief Justice of the United States. Each of these figures has significant roles but none match the current Vice President's position.
