The Senate President is the presiding officer of the U.S. Senate, responsible for maintaining order during debates and ensuring that rules are followed. This position is typically held by a member of the majority party and is elected by fellow senators. The Senate President also plays a key role in legislative decision-making and represents the Senate in official functions. In addition to presiding over sessions, the Senate President has the authority to appoint committee members and schedule votes on legislation. If the Vice President of the United States is unavailable, the Senate President pro tempore, usually the longest-serving senator of the majority party, assumes these duties.
