The US House of Representatives approved a Democratic-backed resolution on Wednesday aimed at restricting President Donald Trump from pursuing further military action against Iran absent congressional consent.

The measure cleared the chamber by a 215-208 margin, drawing support from four Republicans.

House Position Shifts on Iran War Powers

The outcome reflects a notable change in the House, where earlier war powers resolutions had been defeated.

Prior attempts fell short by tight margins, including a 212-212 tie last month. Republican leaders had also withdrawn a similar proposal in May amid fears of defections and absences.

Backers insist Congress holds constitutional war-declaring authority and must have greater input on sustained military operations.

Senate Moves on Comparable Measure

The House vote follows Senate action last month that advanced a parallel resolution through a procedural step.

That measure secured support from four Republican senators, signaling mounting bipartisan concern over the conflict's course and length.

Although the House result challenges the administration, the resolution's prospects remain unclear. The Senate must still approve matching legislation, and any final bill would likely encounter White House opposition.

Vote Takes Place Amid Iran Negotiations

The House action unfolds while the Trump administration continues diplomatic outreach to Iran.

Trump stated at the White House that talks with Tehran are advancing well and a potential agreement could emerge by the weekend.

The president added that any deal would require US control over Iran's highly enriched uranium stockpile and noted military options would stay available if diplomacy stalls.

The administration favors negotiations yet maintains connected military operations.

Capitol Hill Unease Crosses Party Lines

The vote reveals growing bipartisan discomfort with the war's direction, even among some Republicans who typically back Trump's foreign policy.

Resolution supporters seek expanded congressional oversight of military scope and duration, while opponents contend that curbing presidential authority could harm national security and weaken negotiating strength.

The House decision highlights how debate over the conflict now spans party lines as lawmakers evaluate costs, risks and objectives.
