Republicans hold a 53-47 Senate majority in the 119th Congress, enabling use of the budget reconciliation process to advance fiscal measures with a simple majority and bypass the filibuster. After enacting two prior reconciliation packages—one expansive domestic bill in 2025 and a June 2026 immigration enforcement measure—House Republicans approved a July 2026 budget resolution framework for a third package focused on defense spending, farm aid, Iran-related funding, and election provisions. Senate Majority Leader John Thune has delayed action, citing the need to prioritize a September government funding deal to avert a shutdown and concerns over internal divisions, Byrd Rule compliance, and proximity to the November 2026 midterms. Pressure from the House and White House continues, with any Senate vote likely tied to fiscal deadlines or post-election timing.
