How Each House Member Voted on the Iran War Powers Resolution

A vote on this measure was originally scheduled for last month but was pulled by House Republican leaders after it became clear they lacked the votes at the time to defeat it because of several members’ absences. Several Republicans were also absent on Wednesday, but party leaders were unable to delay the vote any longer.

Votes fell mostly along party lines, with the exception of four Republicans, who voted with Democrats to pass the measure. Representative Jared Golden, Democrat of Maine, who had previously voted with Republicans, flipped and voted with his party.

Republicans who voted against their party

The House vote came after four Senate Republicans last month broke from their party to advance a measure to assert the legislature’s role in authorizing the war. The Senate had rejected seven other similar measures, but Republicans in both chambers have expressed increased uneasiness with the conflict as it wears on.

Even if a war powers resolution passed in both the House and Senate, it would be subject to an all-but-certain veto by Mr. Trump, which would need a two-thirds majority in both chambers to override. Beyond that, the president and his senior aides have frequently dismissed efforts by Congress to rein in his war powers, saying they are unconstitutional.
