Kentucky Republican Sen. Mitch McConnell announced that he will assume the role of chairman of both the Defense Appropriations Subcommittee and the Senate Rules Committee when the new Congress convenes in January. McConnell highlighted the importance of national security, emphasizing that America faces significant threats, and stressed the responsibility of the new Republican majority to safeguard U.S. leadership.
Sen. Susan Collins, currently the top Republican on the Defense Subcommittee, is expected to become chair of the full Appropriations Committee, and McConnell expressed his eagerness to collaborate with her on shared goals. The exact future of Collins’ role within the subcommittees is still unclear.
McConnell also emphasized his commitment to defending the Senate institution and protecting political speech through his leadership of the Rules Committee. He acknowledged Sen. Deb Fischer’s outstanding work and stated that she would continue to be a key partner in advancing these causes.
In a leadership shift, South Dakota’s Sen. John Thune was elected to take over as the Senate Republican leader, succeeding McConnell. Although McConnell will step down from leadership, he will remain an active member of both committees. McConnell is up for reelection in 2026 but has not announced whether he intends to seek another term or retire.
