The U.S. House approved a war powers resolution limiting President Trump's authority to continue military operations against Iran, with a 220-204 vote that included seven Republican supporters.
The U.S. House of Representatives voted 220-204 to adopt a war powers resolution that would require congressional approval for continued military action against Iran, marking the third such measure this year. Seven Republicans joined all Democrats in supporting the resolution, three of whom voted for it for the first time.
"With the negotiating window closed, sustained combat operations now require congressional authorization," Iowa Rep. Zach Nunn said, adding that he would not back another open-ended war.
Republican Rep. Brian Mast, chair of the House Foreign Affairs Committee, questioned which military assets Democrats would seek to withdraw from the region, noting that Iran remains a threat to the United States.
The resolution is unlikely to reach the president’s desk, as President Trump is expected to veto it. The vote comes as lawmakers prepare for the upcoming midterm elections, where the Iran conflict has become a prominent campaign issue.
A Congressional Budget Office report released Tuesday estimated the six-month war has cost $38 billion and could add $3 billion each month, with a projected inflation impact of 0.5 percentage points in early 2027. An AP-NORC poll in July found a majority of Americans view the war as not worthwhile.
Previous attempts by Congress to limit the president’s war powers on Iran have been blocked by presidential veto threats, highlighting the ongoing tension between legislative authority to declare war and executive power as commander-in-chief.
