The House voted 220-204 to end the Iran war, its third such vote. Will the Senate pass its own war powers resolution before Oct 1?

The Senate on Sept. 24, 2026, voted 49-50 against a war powers resolution that would have directed President Trump to end U.S. military action against Iran absent congressional authorization, falling one vote short of passage. Four Republicans — Rand Paul, Susan Collins, Lisa Murkowski and Thom Tillis — joined nearly all Democrats in favor, while Democrat John Fetterman voted no and Angela Alsobrooks did not vote. The vote followed the House's Sept. 16 passage of its own resolution, 220-204, the third such House vote, with seven Republicans breaking ranks to support it. Because the Senate measure failed and no subsequent vote occurred before Oct. 1, the Senate did not pass its own war powers resolution by the question's deadline. Democrats had forced repeated votes in both chambers through 2026 to put Republicans on record over the continuing conflict, which drew narrowing but still insufficient GOP support in the Senate. Predict Six's community leaned toward "Yes" at 54%, anticipating Senate passage. The actual outcome was "No," meaning the community's majority prediction was wrong.
