Majority Leader / Minority Leader
The Senate Republican and Democratic floor leaders are elected by the members of their party in the Senate at the beginning of each Congress. Depending on which party is in power, one serves as majority leader and the other as minority leader. The leaders serve as spokespersons for their party's positions on issues. The majority leader schedules the daily legislative program and fashions the unanimous consent agreements that govern the time for debate.
The majority leader has the right to be called upon first if several senators are seeking recognition by the presiding officer, which enables him to offer motions or amendments before any other senator.
The positions of Majority Leader and Minority Leader are held by two United States senators and members of the party leadership of the United States Senate. They serve as the chief spokespersons for their respective political parties holding the majority and the minority in the United States Senate. They are each elected as majority leader and minority leader by the senators of their party caucuses: the Senate Democratic Caucus and the Senate Republican Conference.
By Senate precedent, the presiding officer gives the Majority Leader priority in obtaining recognition to speak on the floor of the Senate. The majority leader serves as the chief representative of their party in the Senate, and is considered the most powerful member of the Senate. They also serve as the chief representative of their party in the entire Congress if the House of Representatives, and thus the office of the speaker of the House, is controlled by the opposition party. The Senate's executive and legislative business is also managed and scheduled by the majority leader.
多数党领袖、少数党领袖
参议院共和党和民主党基层领导人在每次国会开始时由他们在参议院的政党成员选举产生。根据哪个政党执政，一个担任多数党领袖，另一个担任少数党领袖。领导人是本党在问题上的立场的发言人。多数党领袖安排日常立法计划并制定一致同意协议，以管理辩论时间。
如果有几位参议员寻求议长的承认，多数党领袖有权首先被召集，这使他能够在任何其他参议员之前提出动议或修正案。
多数党领袖和少数党领袖的职位由两名美国参议员和美国参议院党的领导成员担任。他们担任各自在美国参议院中占多数和少数的政党的首席发言人。他们每个人都由各自政党核心小组的参议员选举为多数党领袖和少数党领袖：参议院民主党核心小组和参议院共和党会议。
根据参议院的先例，议长赋予多数党领袖优先权，以获得在参议院发言的认可。多数党领袖是其政党在参议院的首席代表，被认为是参议院最有权势的成员。如果众议院以及众议院议长的办公室由反对党控制，他们还担任其政党在整个国会中的首席代表。参议院的行政和立法事务也由多数党领袖管理和安排。
