The Senate on Tuesday approved a war powers resolution seeking to block U.S. military action against Iran, marking the first time the chamber has taken such a step. The vote, 50-48, signals growing concerns among lawmakers about the administration's handling of the conflict and its funding. The resolution, largely symbolic, received support from four Republican senators: Lisa Murkowski of Alaska, Susan Collins of Maine, Rand Paul of Kentucky, and Bill Cassidy of Louisiana.
President Donald Trump reacted negatively to the vote on his Truth Social platform, calling it "poorly timed and meaningless" and stating it "provided aid and comfort" to Iran. He also criticized the Republican senators who voted in favor, saying they made his job more difficult.
Senate Democratic Leader Chuck Schumer criticized the outcome, stating that "the vast majority of Senate Republicans sided with Trump and his war instead of the American people." He further characterized the situation as "Trump's historic blunder in Iran" and one of America's worst foreign policy forays.
The passage of the resolution comes as the Pentagon is seeking approximately $80 billion from Congress, primarily for the Iran conflict and to backfill munitions and stockpiles. The war's estimated cost has been a point of contention, with experts suggesting an overall price tag higher than the Pentagon's initial estimates.
The House of Representatives had previously approved a similar war powers resolution earlier this month, with four Republicans joining all Democrats in the vote, despite objections from House leadership. While these resolutions do not carry the full force of law and would likely face a presidential veto, their passage represents a significant symbolic statement from Congress.
Sen. Tim Kaine, a leading Democrat on this issue, suggested that the current pause in active conflict provides an opportune moment for Congress to re-evaluate the path forward.
Concerns have also been raised about the terms of a memorandum of understanding Trump signed, which initiates a 60-day period for reaching a broader agreement on Iran's nuclear program. Republicans have particularly objected to a $300 billion fund allocated to help Iran rebuild, a sum significantly larger than previous funding provided under the Obama administration's 2015 Iran deal. Sen. Ted Cruz has publicly stated that he believes President Trump is receiving poor advice regarding Iran.
Democrats have repeatedly forced votes on war powers resolutions concerning Iran since U.S. and Israeli missile strikes on Feb. 28. These efforts have consistently fallen short of the majority needed in the narrowly divided Senate until Tuesday's vote. The absence of key Republican senators, including Mitch McConnell, contributed to the outcome.
President Trump is scheduled to meet with Republican senators on Wednesday. This meeting follows Vice President JD Vance's overseas efforts to negotiate with Iran regarding its nuclear ambitions, which were among the stated rationales for the military action. The administration is seeking substantial defense funding increases as part of its broader budget request, including a significant amount within a proposed budget reconciliation package.
