Iowa Republicans Break Ranks as House Votes to Rein In Iran War
The House voted Tuesday to direct President Donald Trump to end the war in Iran or seek explicit congressional authorization to continue it, with two Iowa Republicans joining Democrats in a bipartisan rebuke of the administration's handling of the conflict. The 220-204 vote marks the third time the chamber has taken such action, reflecting growing frustration on Capitol Hill as fighting continues, gas prices climb, and voters grow increasingly weary of the campaign.
What did the House resolution do?
The resolution, offered by Rep. Seth Moulton, D-Mass., a combat veteran, does not carry the force of law. Instead, it seeks to compel the administration to either halt military operations against Iran or win a formal vote of Congress approving them. Moulton argued the war with Iran has not only failed but backfired, pointing to depleted munitions stockpiles, rising energy costs, and a conflict far longer than the weekslong operation Trump and Defense Secretary Pete Hegseth promised when bombing began in late February.
Which Iowa lawmakers voted against the war?
Reps. Mariannette Miller-Meeks and Zach Nunn, both Iowa Republicans, broke with the majority of their party to support the resolution. Both previously opposed efforts to restrict military operations against Iran, making Tuesday's vote a notable shift.
Nunn, also a combat veteran, said in a statement after the vote that sustained combat operations now require congressional authorization. He noted that two of the 18 U.S. service members killed since the war began were from Iowa.
Congress owes them, their families and every American in uniform clear objectives and constitutional oversight, Nunn said.
Why are Republicans growing frustrated with the war?
The vote comes as polls show the conflict is increasingly unpopular with the voters Republicans need to maintain their majorities in Congress. A national poll conducted this month by The New York Times and Siena University found that the war, which has driven gas prices above $4 a gallon, is weighing down the president's approval rating. More than three-quarters of independent voters said they disapproved of his handling of the war, along with nearly a quarter of those who supported Trump in 2024.
Seven Republicans joined Democrats in supporting the resolution, including Reps. Tom Barrett of Michigan, Warren Davidson of Ohio, Brian Fitzpatrick of Pennsylvania, Thomas Massie of Kentucky, and Nancy Mace of South Carolina, alongside Miller-Meeks and Nunn.
What are the costs of the Iran war?
The direct costs of the war from Feb. 28 through Aug. 1 reached roughly $38 billion, the Congressional Budget Office reported Tuesday. That figure is limited because the Pentagon declined to provide details about how much had been spent.
The economic toll is being felt across the country. The average cost of diesel fuel reached a record $6 per gallon last week, and rising energy prices are affecting air travel, farming, and a number of sectors with ripple effects for American consumers.
Is the Senate also pushing back?
Sen. Thom Tillis, R-N.C., who has opposed efforts to rein in Trump on the war, said Tuesday he would now support such a measure.
It is time to be clear on the strategic objectives and start measuring results, Tillis said. And that's not something that we've had since they started the conflict.
Tillis initially backed the administration's assertion that congressional approval was not necessary, maintaining Trump was within his constitutional authority to direct the military for 60 to 90 days without congressional approval. That period passed in the spring, but Tillis still deferred to the president. Now, he says, since the administration began characterizing the conflict as a war in mid-July, a two-month clock for Trump to secure authorization has lapsed.
What happens next?
Though the vote was the fifth time a bipartisan majority in one chamber of Congress has voted to direct Trump to end the war, the president continues to refuse to involve the legislative branch and shows no signs of winding down the military campaign. Democrats who backed the measure said the president had circumvented Congress in violation of the Constitution to unilaterally undertake an overseas war with no clear direction, timetable, or set of objectives.
Rep. Gregory W. Meeks of New York, the top Democrat on the Foreign Affairs Committee, said during debate Monday evening that Congress has not authorized a war with Iran.
This Congress has not authorized a war with Iran, and yet this administration has kept our troops in harm's way without a declaration of war, without an authorization from Congress and without any plan for how to win or end the war, Meeks said.
The Times/Siena poll found that only 31% of likely voters approve of the war with Iran. Among Republicans, that figure is much higher, with 77% in favor. But among independent voters, a group that could play a critical role in the midterm elections, only 21% approve of the war.
