Who serves as the president of the Senate?

The Vice President of the United States serves as the president of the Senate. This role is specified in the U.S. Constitution, which designates the Vice President to oversee and preside over the Senate's sessions. While the Vice President does not participate in debates and only votes in the case of a tie, this position is significant for ensuring that the Senate operates smoothly within its constitutional framework. The Vice President's ability to cast tie-breaking votes can be crucial in close legislative decisions, emphasizing the importance of this role in the legislative process.

In contrast to the Vice President, the other figures listed have different responsibilities within the Senate or House of Representatives. The Speaker of the House is responsible for presiding over the House of Representatives, the President Pro Tempore typically serves as a ceremonial leader of the Senate in the Vice President's absence, and the Majority Leader focuses on managing the legislative agenda of the majority party in the Senate. Each of these positions plays a vital role in the operation of the government but does not fulfill the specific constitutional role assigned to the Vice President in relation to the Senate.
