As of the start of the 119th Congress in January 2025, the Republican Party controls the U.S. Senate. In the 2024 elections, Republicans gained a three- seat majority in the Senate, securing control along with maintaining their majority in the House of Representatives and winning the presidency
. This gives Republicans a trifecta in federal government control for the first time since 2017
. The Senate consists of 100 members, two from each state, serving staggered six-year terms. The vice president of the United States serves as the president of the Senate and may cast tie-breaking votes. The Senate majority party elects a president pro tempore, traditionally the most senior member of the majority party, who presides in the vice president's absence. The Senate majority leader, from the controlling party, manages legislative business and scheduling
. In summary, Republicans hold the majority in the Senate as of 2025, controlling the chamber and its leadership positions, enabling them to advance their legislative agenda and confirm presidential appointments
