House Republicans cancel a scheduled vote on a war powers resolution intended to require President Donald Trump to end U.S. hostilities with Iran, with the House not holding the measure as planned. The cancellation, reported by multiple outlets, postpones the effort and is described as part of a broader pattern in which support in Congress for Trump’s Iran strategy is weakening.

Earlier, the U.S. Senate advanced a similar war powers resolution for the first time during this phase of the conflict. The Senate voted to take up the measure after a bipartisan mix of lawmakers supported moving it forward; Senate figures cited in reports include a 50–47 vote and earlier attempts that failed narrowly.

The measures are framed under the 1973 War Powers Act, which allows lawmakers to push to end or limit military actions not authorized by Congress. Support for the resolution grows as some Republican senators and representatives increasingly back the idea of asserting congressional authority over the war powers process. Some reports link shifts in Republican voting patterns to attendance and political dynamics within the party.

Overall, the House delay occurs as the Senate moves the issue forward, keeping pressure on Trump’s ability to continue military operations without congressional authorization.
