WASHINGTON, D.C., United States — The United States House of Representatives has passed a resolution seeking to restrict President Donald Trump from undertaking further military action against Iran without congressional approval, marking the latest effort by lawmakers to reassert Congress’s constitutional authority over war powers.
The measure passed by a narrow 215-208 vote on Wednesday, with four Republican lawmakers breaking ranks to join Democrats in support of the resolution. The vote underscores growing unease within sections of Congress over the administration’s handling of the conflict with Iran and reflects broader divisions within Trump’s Republican Party.
Although the resolution represents a significant political setback for the White House, its future remains uncertain. The measure must still be approved by the Republican-controlled Senate before it can become law, and even then its practical effect on ongoing military operations could be limited.
The House vote marks the fourth attempt by lawmakers to curtail Trump’s authority to conduct military operations against Iran without explicit authorisation from Congress.
Bipartisan concerns over war powers
Supporters of the resolution argue that the U.S. Constitution grants Congress—not the president—the authority to declare war, and that any prolonged military engagement requires legislative approval.
Among the Republicans who voted in favour were Representatives Thomas Massie, Brian Fitzpatrick, Tom Barrett, and Warren Davidson, joining a united Democratic caucus in backing the measure.
Michigan Republican Tom Barrett defended his decision, saying lawmakers have a responsibility to safeguard congressional authority on matters of war.
“Congress alone declares war. That’s something certainly we need to be protective of,” Barrett said after the vote.
Asked whether he feared political repercussions from President Trump, Barrett replied that he was prepared to stand by his position.
“I vote my conscience for what I think is right and am willing to accept that.”
Democratic Representative Gregory Meeks, the ranking member on the House Foreign Affairs Committee and a co-sponsor of the resolution, described the vote as a rare bipartisan challenge to the administration’s military strategy.
“This is a significant bipartisan rebuke of President Trump’s illegal and costly war in Iran and the first step toward ending it once and for all,” Meeks said.
Conflict continues despite ceasefire efforts
The latest congressional action comes against the backdrop of a conflict that has heightened tensions across the Middle East and disrupted global energy markets.
The United States and Israel launched military strikes against Iran on February 28, prompting retaliatory attacks by Tehran against Israel and U.S.-aligned interests in the Gulf region.
The conflict escalated further after Iran effectively closed the Strait of Hormuz, one of the world’s most strategically important shipping routes through which a significant share of global oil exports passes.
Washington subsequently announced restrictions targeting maritime traffic linked to Iran, further increasing tensions in the region.
Although the United States and Iran reached an initial ceasefire agreement in April, military exchanges have continued intermittently, raising concerns about the durability of the truce and the prospects for a diplomatic settlement.
Recent reports indicate that both sides have continued to carry out military operations despite ongoing negotiations.
Trump insists negotiations are progressing
President Trump has maintained that diplomatic efforts to end the conflict are advancing and suggested that a broader agreement could be reached soon.
Speaking at the White House before the House vote, Trump said discussions with Iran were progressing positively despite the continued military exchanges.
“We hit them pretty hard the night before, and actually last night,” Trump told reporters, referring to recent strikes.
He argued that some of Iran’s actions were retaliatory responses to U.S. operations and insisted that negotiators were close to reaching a formal agreement.
“In theory they’re pretty close to signing a paper. We’ve actually gotten along with them very well,” Trump said.

The president added that members of his administration remained committed to ending the conflict through diplomacy rather than prolonged military confrontation.
Senate battle looms
Attention now shifts to the Senate, where a similar resolution previously advanced through procedural stages but has yet to secure a full floor vote.
Political analysts say the outcome will test the willingness of Republican senators to challenge the White House on national security matters, particularly as concerns grow over the costs and risks associated with an open-ended military engagement in the Middle East.
The House vote nevertheless signals increasing bipartisan scrutiny of the administration’s Iran policy and reflects broader questions about the balance of power between Congress and the presidency during times of conflict.
As lawmakers debate the next steps, the future of U.S. military involvement in Iran may ultimately depend as much on political negotiations in Washington as on diplomatic talks in the Middle East.
