The US Senate on Thursday rejected a House-passed resolution that sought to require the withdrawal of American forces from hostilities with Iran unless Congress authorised continued military action. The 49-50 vote preserved President Donald Trump’s current authority to continue the military campaign, while exposing divisions among lawmakers over the war’s duration, cost and objectives.
Washington, Sept 2026 : The US Senate narrowly rejected a resolution seeking to end American military involvement in the war against Iran unless Congress provided specific authorisation, in a closely divided vote that highlighted continuing disagreement over congressional war powers and the Trump administration’s military strategy.
The Senate voted 49-50 against H. Con. Res. 89, according to the official Senate roll call. The resolution, which had already passed the House, would have directed the removal of US Armed Forces from hostilities with Iran under the 1973 War Powers Resolution unless Congress declared war or enacted a specific authorisation for the use of military force.
Four Republican senators — Susan Collins, Lisa Murkowski, Rand Paul and Thom Tillis — joined Democrats in voting for the measure. Democratic Senator John Fetterman voted against it, while Senator Angela Alsobrooks did not vote. The outcome therefore fell one vote short of an evenly divided Senate.
The defeat means the House-passed resolution will not advance through the Senate. It represented the latest congressional effort to assert a greater role for lawmakers in decisions involving US military operations against Iran.
The vote came after more than 200 days of conflict and amid growing debate in Congress over the duration of the military campaign, its financial implications and its impact on fuel prices.
Senate Democratic Leader Chuck Schumer said Democrats had now forced 14 votes related to ending the conflict. He criticised Senate Republicans for rejecting the latest War Powers Resolution and argued that the war was imposing significant costs on Americans.
“Senate Republicans voted down today’s War Powers Resolution,” Schumer said, arguing that lawmakers should address the financial and broader consequences of the conflict.
Schumer’s office also alleged that at least 19 US service members had been killed and that the war had cost taxpayers more than $43 billion. Those figures were presented by the Democratic leader’s office and were not independently established in the material available for the vote.
The Senate action followed a closed-door briefing by Admiral Brad Cooper, commander of US Central Command, for members of the Senate Armed Services Committee. Republican senators who emerged from the briefing generally expressed support for continuing the administration’s approach.
Republican Senator Mike Rounds said the briefing had outlined the administration’s available options and appeared to provide a strategy aimed at continuing to weaken Iran’s economic capacity to wage war.
Senator Joni Ernst acknowledged concerns over the economic impact of the conflict but said she supported the President. She also called for a clearer explanation from the administration about how the war could eventually be brought to an end.
Democrats offered a different assessment of the classified briefing. Senator Richard Blumenthal said he did not see a clear path towards an end-state and argued that the American public should understand the potential costs and risks associated with the military strategy.
The vote nevertheless demonstrated that opposition to the administration’s Iran policy is not confined to one party. Four Republicans crossed party lines to support the resolution, while one Democrat voted against it.
The Senate had previously considered other Iran-related War Powers measures during 2026. In June, it adopted H. Con. Res. 86 by 50-48, while subsequent efforts to advance other resolutions were also defeated.
The latest 49-50 vote leaves the current US military campaign against Iran in place and underscores the continuing congressional debate over the constitutional balance between presidential authority and Congress’s power over decisions involving war and military force.
