House rejects bid to force Trump to end Iran hostilities

The House fell one vote short of forcing President Donald Trump to end U.S. military hostilities with Iran, a narrow defeat that underscored how little room Congress has to restrain an escalating conflict when most Republicans stay aligned with the White House. The Democratic-led war powers resolution failed 213-214, with one member voting present.

Rep. Gregory Meeks of New York, the top Democrat on the House Foreign Affairs Committee, introduced the measure as a test of Congress’s constitutional authority over war. The House Concurrent Resolution 40 would have directed Trump to remove U.S. armed forces from hostilities with Iran unless Congress explicitly authorized them. Because it was a concurrent resolution, it would have stated Congress’s position rather than becoming law, but Democrats said it was intended to trigger the War Powers Resolution process and force a formal check on the administration.

Only one Republican, Rep. Thomas Massie of Kentucky, voted with nearly all Democrats. Warren Davidson of Ohio has also broken with most Republicans in earlier Iran war powers votes, but the broader GOP conference again rallied behind Trump. That alignment was enough to kill the measure and leave the White House with no new congressional constraint on the military campaign.

Meeks cast the vote as a constitutional question about whether Congress, not the president alone, can authorize sustained hostilities. Opponents argued the resolution would weaken Trump’s ability to respond to threats from Iran. The split reflected a familiar divide in Washington, where lawmakers may object to military action in principle but still stop short of crossing the president when the stakes are framed as national security.

The defeat also came one day after the Senate blocked a similar effort, showing that pushback against the Iran campaign has not translated into enough votes in either chamber. A related Senate joint resolution, S.J.Res.118, was introduced on March 5, 2026 by Sens. Tim Kaine, Chris Murphy, Adam Schiff and Cory Booker, signaling that critics are still trying to use Congress’s war powers even after this setback. For now, the practical checks left are political pressure, continued Senate action and any future effort to force a new authorization before the conflict deepens further.
