  • Senate rejects war powers resolution on Iran 47-53

  • House expected to vote on similar resolution Thursday

The Senate rejected a war powers resolution that sought to block President Trump from using further military force against Iran, voting 47 to 53. The resolution, led by Senator Tim Kaine (D-Va.) and cosponsored by Senator Rand Paul (R-Ky.), aimed to direct the removal of U.S. armed forces from hostilities within or against Iran without congressional authorization.

The vote fell short of the simple majority needed to advance, with only Republican Sen. Rand Paul supporting it. Democratic Sen. John Fetterman of Pennsylvania voted against the measure, which required at least five Republican votes to pass. The resolution is the second attempt in less than a year by Senator Kaine to limit Trump's military actions against Iran.

The Senate had previously voted down a similar effort in June 2025 after the U.S. bombed three Iranian nuclear sites. The recent vote came amid heightened tensions and a massive military operation that began over the weekend, adding urgency to the debate.

Senate Minority Leader Chuck Schumer (D-N.Y.) expressed concerns about "mission creep" and shifting goals, while Republican Sen. Todd Young of Indiana encouraged Congress to take on a greater oversight role but ultimately voted against the resolution. Defense Secretary Pete Hegseth stated that the operation is "just getting started" and could last several weeks.

Democrats emerged from a classified briefing with Trump administration officials unsatisfied, expressing fears of more American casualties and the potential insertion of ground troops. A CBS News poll found that most Americans disapprove of the war with Iran and believe the Trump administration has not clearly explained its goals.

The Constitution grants Congress the authority to declare war, and the 1973 War Powers Resolution was passed as a check on presidential power to enter armed conflict without congressional consent. Despite the resolution's failure, Senator Kaine indicated he may continue forcing votes on the issue in the coming weeks.
