House votes to curb Trump's Iran war powers as four Republicans break ranks, but veto looms

A bipartisan rebuke

The US House of Representatives voted 215 to 208 on Wednesday to approve a war powers resolution directing President Donald Trump to end American involvement in hostilities against Iran. Four Republicans — Thomas Massie of Kentucky, Tom Barrett of Michigan, Warren Davidson of Ohio and Brian Fitzpatrick of Pennsylvania — joined Democrats to push the measure over the majority threshold, defying party leadership. The vote represents the first time since the conflict began in late February that Congress has succeeded in passing legislation aimed at constraining the military campaign.

We are trapped in something that will not end because an incompetent president started it thinking only of his ego without preparing for the consequences.

Trump's response

On Thursday, Trump took to his Truth Social platform to condemn the vote, calling it "unpatriotic" and arguing it disrupted diplomacy. He said the resolution passed "right in the middle of my final negotiations to end the War with the Islamic Republic of Iran." Trump reserved particular scorn for the four Republican defectors, labelling them "GRANDSTANDERS" who "should be ashamed of themselves." He dismissed the resolution as "meaningless."

Who would do such an unpatriotic thing. They know where the negotiations stand.

Constitutional clash

The resolution invokes the War Powers Resolution of 1973, a law passed in the wake of the Vietnam War that requires presidents to obtain congressional authorisation within 60 days of introducing US forces into hostilities. That deadline passed on May 1, more than a month ago. Democrats argue Trump is now in violation of the law. The White House and Republican leadership counter that the president retains broad authority as commander-in-chief and that a ceasefire which took effect on April 8 meant hostilities had effectively ended, despite the continuation of a naval blockade and recent exchanges of limited strikes.

We are not in a situation of hostility — we are engaged with almost exactly the same number of forces that we continuously maintain in the region.

Symbolic but significant

The resolution remains largely symbolic. It must still pass the Senate, where a similar measure received initial procedural approval last month, and would require a two-thirds majority in both chambers to override an almost certain presidential veto. House Speaker Mike Johnson called the resolution "dangerous," arguing it could weaken the US negotiating position. Nevertheless, the vote reflects growing congressional unease, even among Republicans, over a conflict that polls suggest more than 60 percent of voters consider a mistake ahead of November's midterm elections.

Stalled negotiations

Efforts to reach a lasting ceasefire have progressed in fits and starts. The Trump administration has alternated between military threats and promises of a diplomatic breakthrough, with Trump saying on Wednesday that a deal could come by this weekend. Key sticking points include the future of Iran's nuclear programme and control of the Strait of Hormuz. The administration is reportedly seeking a nuclear deal stronger than the 2015 Joint Comprehensive Plan of Action, which Trump withdrew from in 2018, calling it "foolish" and "defective."
