In a historic bipartisan rebuke of the Trump administration’s military engagement in Iran, the U.S. House of Representatives has approved a resolution designed to block President Donald Trump from launching additional offensive military action against Tehran. The final vote tally stood at 215 in favor to 208 against, with four House Republicans breaking ranks with their party leadership to side with a unified Democratic caucus in passing the measure.
This vote marks the fourth formal attempt by the House to curtail the president’s war-making authority in Iran, a conflict critics argue has proceeded without the constitutionally required congressional declaration of war. The House initiative now moves to the Republican-controlled U.S. Senate for consideration, where its path forward remains uncertain. Even if the resolution clears the full Senate, political observers widely note it is unlikely to result in a full halt to U.S. military operations against Iran.
The Senate previously advanced a nearly identical resolution in May, the first such measure to overcome procedural hurdles after seven failed attempts, but it has not yet been scheduled for a full floor vote. Wednesday’s vote comes amid growing public divisions within the Republican Party over Trump’s foreign policy, just one week after a conservative rebellion in Congress forced the White House to scrap a proposed $1.8 billion “anti-weaponization” fund earmarked for political allies.
The four Republican lawmakers who backed the resolution are Thomas Massie, Brian Fitzpatrick, Tom Barrett, and Warren Davidson. Notably, Democratic Representative Jared Golden of Maine, who had opposed earlier iterations of similar measures, also switched his position to support the bill this round. Speaking after the vote, Michigan Republican Tom Barrett emphasized the constitutional principle underpinning his decision, noting “Congress alone declares war, that’s something certainly we need to be protective of.” When asked if he feared political retribution from Trump for his dissenting vote, Barrett added, “I vote my conscience for what I think is right and willing to accept that.”
House Foreign Affairs Committee leading Democrat Gregory Meeks, who co-sponsored the resolution, framed the outcome as a landmark bipartisan push to end what he called Trump’s “illegal and costly war in Iran.” Meeks argued that the president has failed to deliver on the war’s stated public goals, while driving up domestic U.S. fuel prices and complicating diplomatic efforts to resolve tensions over Iran’s nuclear program. “The passage of this [measure] today signals a significant turning point: more and more Republicans are listening to their constituents who do not want another open-ended war in the Middle East,” Meeks said.
The current conflict between the U.S., Iran, and regional allies began in late February, when the U.S. and Israel launched joint airstrikes against Iranian targets. Iran retaliated with attacks on Israel and U.S.-partnered states in the Persian Gulf, and effectively shut down traffic through the Strait of Hormuz — a critical global shipping chokepoint that carries roughly a fifth of the world’s oil supply. In April, the U.S. announced a full naval blockade of commercial traffic moving to and from Iran’s coast, before the two sides reached an initial ceasefire agreement on April 8.
Despite the ceasefire, intermittent hostilities have continued in recent weeks: the U.S. has carried out new strikes on Iranian targets, while Tehran has responded with attacks on Kuwait, a major U.S. ally in the region. Ahead of Wednesday’s House vote, Trump told reporters at the White House that peace negotiations to end the conflict were progressing “very well,” and suggested a final deal could be completed as early as the same weekend. “We hit them pretty hard the night before, and actually last night,” Trump said, referencing recent U.S. strikes. “Some people would say they were slightly provoked because we took a strong action for a different reason, so they were reciprocating.”
The president added that most senior members of his administration support reaching a negotiated end to the conflict “without killing everybody.” “In theory they’re pretty close to signing a paper, we’ve actually gotten along with them very well,” Trump said.
