Seven House Republicans joined forces with Democrats to pass legislation reining in President Trump’s military authority in Iran, delivering a rare bipartisan rebuke to the commander in chief in a 220-204 vote late Tuesday night.

Republicans Split on Constitutional Authority

The defecting Republicans—Reps. Tom Barrett of Michigan, Warren Davidson of Ohio, Brian Fitzpatrick of Pennsylvania, Nancy Mace of South Carolina, Thomas Massie of Kentucky, Marianette Miller-Meeks of Iowa, and Zach Nunn of Iowa—argued Congress must formally declare war under constitutional law. All 213 voting Democrats supported the measure introduced by Rep. Seth Moulton of Massachusetts, while 203 Republicans and one Independent opposed it.

The dissenters cite the War Powers Resolution of 1973, which limits presidential military engagement to 60 days without congressional authorization, plus 30 additional days for withdrawal. These lawmakers contend that timeframe expired months ago. Barrett told Fox News Digital he has remained consistent since the war powers provision deadline passed.

Administration Defends Military Operation

The Trump administration maintains the president operates within constitutional authority as commander in chief. Officials argue the resolution improperly restricts presidential power to protect American forces and national security interests abroad. Rep. Marlin Stutzman of Indiana defended the president’s approach, stating Trump has managed the situation effectively and fulfilled his promise to prevent Iran from obtaining nuclear weapons.

The conflict has become divisive heading into midterm elections, with Democrats accusing the administration of engaging in another prolonged military commitment. Lawmakers and analysts also blame the Iran operation for rising gas prices, expected to dominate voter concerns. The controversy prompted Massie to attempt forcing a vote on impeaching Secretary of War Pete Hegseth.

What Happens Next

The Senate passed similar legislation in June with Republican defections. However, Trump opposes such measures and would likely veto any bill reaching his desk. Even with bipartisan support in both chambers, overriding a presidential veto requires a two-thirds majority—an unlikely outcome given that most Republicans continue supporting the president’s Iran policy. The dispute highlights ongoing tension between executive authority and congressional war powers that dates back decades.
