List of United States senators in the 118th Congress

Last updated

This is a complete list of United States senators during the 118th United States Congress listed by seniority, from January 3, 2023, to January 3, 2025. It is a historical listing and will contain people who have not served the entire two-year Congress should anyone resign, die, or be expelled.

Contents

Order of service is based on the commencement of the senator's first term. Behind this is former service as a senator (only giving the senator seniority within his or her new incoming class), service as vice president, a House member, a cabinet secretary, or a governor of a state. The final factor is the population of the senator's state. [1] [2] [3] [4] [5] If two senators are tied on all factors, as in the case of Jon Ossoff and Raphael Warnock, the senator elected to the full term is the senior senator. [6] [7]

In this Congress, the most junior senior senator is Jon Ossoff, and Maria Cantwell is the most senior junior senator.

United States senators are conventionally ranked by the length of their tenure in the Senate. The senator in each U.S. state with the longer time in office is known as the senior senator; the other is the junior senator. This convention has no official standing, though seniority confers several benefits, including preference in the choice of committee assignments and physical offices. When senators have been in office for the same length of time, a number of tiebreakers, including previous offices held, are used to determine seniority. By tradition, the longest serving senator of the majority party is named president pro tempore of the Senate, the second-highest office in the Senate and the third in the line of succession to the presidency of the United States.
