Senate
Officers
The vice president acts as the president of the Senate. In the vice president's absence, that position is filled by the president pro tempore, who is usually the most senior senator of the majority party. The majority leader has significant powers in the appointment of majority senators to committees. Political parties also elect majority and minority leaders to lead their efforts in the Senate. They are assisted by an assistant floor leader (whip) and a party secretary.
Other Senate officers include the secretary, who oversees Senate finances and official Senate pronouncements related to IMPEACHMENT proceedings and treaty ratification, and the sergeant at arms, who serves as the law enforcement and protocol officer and organizes ceremonial functions.
