US House votes to end Iran war, 7 Republicans join in favor

The U.S. House of Representatives voted on Tuesday, September 15, 2026, to approve a war powers resolution aimed at ending the ongoing conflict with Iran. The measure passed with a vote of 220-204, marking the third time the House has advanced such a resolution. Notably, seven Republican lawmakers broke ranks to join all voting Democrats in supporting the resolution, with three of those Republicans voting in favor for the first time.

The resolution seeks to restrict President Donald Trump's authority to continue military actions in Iran without explicit congressional authorization. Despite repeated attempts by the House to curb presidential war powers, none of these resolutions have reached the president's desk, where they would likely face a veto. The vote occurred as the conflict, which began on February 28, entered its seventh month, and just hours after a Congressional Budget Office report estimated the war had already cost approximately $38 billion through August 1.

This latest vote is expected to be the final House action on the Iran war before the upcoming midterm elections, where the conflict and its associated costs are anticipated to be significant issues for voters.
