WASHINGTON — As the November midterms approach, vulnerable U.S. House Republicans voted late Tuesday to require congressional approval for President Donald Trump to continue his war in Iran.

Seven Republicans broke ranks and joined all Democrats to pass a War Powers Resolution sponsored by Rep. Seth Moulton, a Massachusetts Democrat. Tuesday’s vote marked the third time since June that the House passed a measure to curb Trump’s military powers in Iran. The war has dragged on for over half a year.

The vote came as diesel prices reached a record high of $6.31 per gallon in the United States, and gas hovered at an average of nearly $4.37 a gallon Wednesday, according to AAA. 

Global oil markets have been rocked since Iranian officials effectively shut the Strait of Hormuz, a major petroleum trade route. The conflict has since expanded, and Iranian-backed Houthi rebels are slowing traffic through another major trade passage, the Bab-al Mandab Strait.

The resolution passed, 220-204, despite Republicans’ narrow majority in the chamber. GOP House members who voted for the Iran War Powers Resolution for the first time included Zach Nunn and Marianette Miller-Meeks of Iowa, and Nancy Mace of South Carolina.

Nunn and Miller-Meeks both face tough reelection bids in Iowa. The Cook Political Report with Amy Walter rates both races as “toss-ups.”

Mace lost her South Carolina gubernatorial primary bid in June and is not seeking reelection to the House.

‘Open-ended war’

Nunn posted on social media Tuesday that, as a U.S. Air Force veteran who flew missions in the Middle East, he could not support “another open-ended war,” though he still believes the Islamic Republic “must be held accountable for killing Americans, supporting terrorism, threatening the Strait of Hormuz, and pursuing nuclear weapons.” 

Presidents have a 60-day period to pursue military action with congressional approval, but that window has passed, he added.

“Iowa has already paid a devastating price, including two service members killed by an Iranian drone in Kuwait,” Nunn wrote on X late Tuesday night. “Congress owes them, their families, and every American in uniform clear objectives and constitutional oversight. … We can defend Americans, pressure Iran, and pursue peace while ensuring Congress fulfills its constitutional responsibility.” 

Miller-Meeks posted Wednesday morning that with her 24 years served in the Army, she remains skeptical of Trump’s actions in Iran. 

“I said it in March: the mission had to stay focused and limited, because Americans do not want another forever war. I will not vote to keep our soldiers in an open-ended war, with Iowans paying too much at the pump,” Miller-Meeks wrote on X.

“The Iranian regime and its nuclear ambitions have been defanged,” she continued. “The President needs to present a plan to Congress and the American people for how this ends so we can focus on bringing our soldiers home and lowering prices.”

Third House vote

Nunn, Miller-Meeks and Mace joined House Republican Reps. Thomas Massie of Kentucky, Tom Barrett of Michigan, Warren Davidson of Ohio, and Brian Fitzpatrick of Pennsylvania, who have now each voted three times to rein in Trump’s actions in the Iran conflict. Massie voted yes an additional time in April, but the measure failed to pass the House then.

Massie on Tuesday introduced eight articles of impeachment against Defense Secretary Pete Hegseth for his handling of the war in Iran.

The Trump administration maintains War Powers Resolutions are unconstitutional and has dismissed the measures passed in both chambers. Similar War Powers Resolutions to stop Trump’s hostilities in Iran cleared procedural votes in the Senate in May and June. The Senate has voted on such measures 13 times.

Congress overrode a veto from President Richard Nixon to enact the War Powers Resolution statute, at the time aimed at reining in Nixon’s actions in Vietnam.
