The U.S. House of Representatives has voted for the third time to restrict President Donald Trump’s authority to continue military operations against Iran without congressional approval, as the conflict enters its seventh month.
The war powers resolution passed 220-204 late Tuesday, with all voting Democrats joined by seven Republicans. The Republican lawmakers were Tom Barrett, Brian Fitzpatrick, Warren Davidson, Thomas Massie, Nancy Mace, Mariannette Miller-Meeks and Zach Nunn. The latest vote attracted more Republican support than the previous attempts in June and July.
The measure would require the administration to end military operations against Iran unless Congress authorises further action. However, the resolution faces an uncertain path in the Senate, which has only two scheduled weeks remaining before the November midterm elections.
The House action comes as the U.S.-Iran conflict continues to affect global energy markets, with the war contributing to higher fuel prices and inflation. The Congressional Budget Office estimates that the conflict has already cost more than $38 billion, with ongoing operations expected to require another $2 billion to $3 billion monthly.
The White House and Republican supporters have maintained that Iran remains a security threat and defended the administration’s military actions, while supporters of the resolution argue that continued hostilities require greater congressional oversight. Previous war-powers resolutions have not reached Trump, who is expected to oppose the latest measure if it reaches his desk.
For the global oil market, the congressional move comes as the conflict continues to coincide with disruptions around key Middle East supply routes, including the Strait of Hormuz and Saudi Arabia’s East-West Pipeline, keeping geopolitical risk firmly embedded in crude and petroleum-product pricing.
