What Happens When a New Congress Begins?

The U.S. Senate relies heavily on tradition and precedent, and the first day of a new Congress is no exception.

When a new Congress convenes in the beginning of January, all the legislation of the past two years has expired (with the exception of treaties), and a new legislative year has begun.

The proceedings of this first day follow a well established, but flexible routine including the swearing in of newly elected and reelected members and the election of the president pro tempore. The Senate may choose to address other administrative issues, or begin with legislative business. The Senate does not have to reorganize itself each new Congress.

Article 1, section 3 of the Constitution provides a system of staggered six-year terms for senators. At the conclusion of each two-year congress, the terms of only one-third of the 100 senators expire, allowing two-thirds of the senators to continue serving without interruption.
