The official Senate roll call on S.J.Res. 104 showed Kentucky Republican Rand Paul as the lone GOP senator to back the measure, while Pennsylvania Democrat John Fetterman was the only member of his party to oppose it. Reuters reported that supporters cast the resolution as an attempt to reassert Congress’ constitutional role in authorizing war, while Republican leaders defended Trump’s ability to keep prosecuting the campaign without a fresh vote.
Why the Iran war powers resolution still matters in the House
The Senate defeat does not end the congressional fight. The text of H.Con.Res. 38 would direct the president to remove U.S. armed forces from unauthorized hostilities in Iran, and the House schedule for Thursday, March 5 shows leaders still plan to complete consideration of the measure.
That vote lands as public skepticism about the war remains high. A Reuters/Ipsos poll found 27% of Americans approved of the strikes, while 43% disapproved and 29% were unsure, suggesting lawmakers will be voting against a backdrop of deep uncertainty over another potentially prolonged Middle East conflict.
For House Republicans, the measure is politically awkward because it forces a choice between backing a president from their own party and defending Congress’ war powers. For Democrats and anti-intervention conservatives, it is one of the few available floor tools to force that choice into the open even after the Senate shut down its own version.
Congress has fought over this before
This is not a one-week argument. Reuters reported in June 2025 that Kaine revived the same core fight during an earlier spike in tensions with Iran, underscoring how long lawmakers have been warning that the White House could widen hostilities without a new authorization from Congress.
The current clash also echoes the aftermath of the U.S. killing of Iranian commander Qassem Soleimani. The Senate approved a similar measure in 2020, but Trump later vetoed that resolution, a reminder that even a bipartisan rebuke can fall short when Congress lacks veto-proof majorities.
That history is why Thursday’s House vote matters even after Wednesday’s Senate loss. A House defeat would reinforce the Senate’s result as an early sign that Congress is still reluctant to restrain Trump on Iran. A House passage would show that opposition to the war still has political life on Capitol Hill, even with the Senate version already blocked.
