The House voted approximately 220–204 on or about September 15, 2026, to direct the removal of U.S. forces from hostilities with Iran under a resolution associated with Rep. Seth Moulton—the third such House war-powers vote since the conflict began.

Key takeaways

  • Tally: 220–204 to direct removal of U.S. forces from hostilities with Iran.
  • Seven Republicans voted yes, including newly listed Miller-Meeks, Nunn, and Mace, plus Barrett, Fitzpatrick, Davidson, and Massie.
  • War began about February 28, 2026; coverage has cited cost estimates of roughly $2–3 billion per month and about $38 billion from Feb. 28 through Aug. 1. Senate path remains unclear.

Third House war-powers vote

This was the third House vote directing an exit from hostilities with Iran. The Moulton resolution again forced members onto the record on whether Congress would reclaim a clearer role over the use of force. CBS, CNN, and the Los Angeles Times have covered the repeated floor fights and the unresolved Senate outlook.

The seven Republican yes votes

Seven Republicans crossed to support the resolution. The yes list includes Miller-Meeks, Nunn, and Mace—newer additions relative to earlier votes—alongside Barrett, Fitzpatrick, Davidson, and Massie. For whip-count watchers, that mix of prior defectors plus fresh names is the signal that GOP unity on the Iran war remains incomplete.

Cost and calendar

Reporting has cited cost estimates of roughly $2–3 billion per month and about $38 billion from February 28 through August 1, 2026, with the war’s start dated around February 28. Those figures come from secondary coverage, not a fresh CBO score published with this vote. What is clear on the Hill: the House has now voted three times to direct removal, while the Senate path is still unclear.
