President Trump launched the war with Iran on February 28. It was supposed to last a few weeks. Congress has never voted to authorize it.

Late on Tuesday, September 15, 2026, the House voted 220 to 204 to order the president to stop. The resolution, H. Con. Res. 93, was pushed by Rep. Seth Moulton of Massachusetts, a Marine who served in Iraq. It passed.

That makes three times. The House passed a resolution like it in June, and again in July. Each time, nearly every Republican voted no. This time Republicans voted 203 to 7 against it.

180 of the members who voted no have a report card on this site — 179 Republicans, plus Kevin Kiley of California, whom the House clerk lists as an independent. Their names are at the bottom of this post.

What the war has cost so far

The same day as the vote, Congress's own nonpartisan budget office put a number on the war for the first time.

According to the Congressional Budget Office's report, as covered by The Washington Sun:

• The war cost the U.S. $38.1 billion through August 1.
• It is costing about $2 billion to $3 billion more every month, and that could rise when the fighting gets heavier.
• $21.7 billion of that went to replacing weapons, including $13.1 billion in missile-defense interceptors. Since June 2025, the U.S. has used between half and two-thirds of its supply of several kinds of those interceptors, and the budget office says rebuilding the stockpile could take five years or more.
• The war will add about half a percentage point to inflation in early 2027, mostly from higher energy prices.
• The budget office now expects oil prices to be 41% higher this year than it forecast before the war started.

The budget office also said its estimate is uncertain for a reason: the Pentagon didn't answer its requests for information. So it had to work from public databases and reports, and it couldn't estimate what it will cost to fix the U.S. bases Iran has hit.

That's the cost to the government. You're paying a second bill at the pump and the grocery store. We broke down what the war has cost the average household earlier this month.

What they were voting on

The War Powers Resolution is a law from the Vietnam era. It says a president needs Congress's approval to keep U.S. forces in sustained fighting past 60 or 90 days. Congress, not the president, gets to decide whether the country stays at war.

A yes vote said: Congress wants the troops out of this fight. A no vote said: the president can keep going on his own.

Like the June and July versions, this one is a concurrent resolution. It doesn't go to the president's desk, and Trump would almost certainly veto anything that did. It's Congress putting its position on the record. That's what makes the no votes telling: a yes vote couldn't end the war on its own, and 180 members we track still wouldn't cast it.

The Speaker's promise

House Speaker Mike Johnson admitted Tuesday that gas prices need to come down. His answer was to wait.

According to the Associated Press, via The Washington Sun, Johnson said the war is entering a "new phase," and that when it does, "anytime gas prices will go down again, the cost of groceries will as well." He said Trump expects that shift after the election, though he added, "I'd love it to happen today."

So the plan is: vote to keep the war going, go home to campaign, and ask voters to believe prices will fall once the ballots are counted.

Brian Mast of Florida, who chairs the House Foreign Affairs Committee, argued against the resolution on the floor. He said Trump is against "forever wars, and that is what he is ending," meaning decades of hostilities with Iran. The war Mast was defending is now more than six months old.

Two Iowa Republicans changed their votes

Seven Republicans voted yes this time. Five of them have report cards here: Tom Barrett of Michigan, Warren Davidson of Ohio, Brian Fitzpatrick of Pennsylvania, and two from Iowa: Mariannette Miller-Meeks and Zach Nunn.

Barrett, Davidson and Fitzpatrick voted yes in July too. Miller-Meeks and Nunn did not. On the July roll call, both voted no. Seven weeks from an election, both switched.

Three Republicans we track who voted no in July didn't vote at all this time: Byron Donalds and Tom Tiffany, who are both running for governor, and Steve Womack of Arkansas.

Congress keeps saying stop

This is not a close call that Congress is still thinking about. The House has now voted three times to end the war. The Senate voted 13 times on ending it by early August. According to the AP, the Senate passed a war powers resolution on its 10th try, and Republican senators reversed course the very next day after Trump berated them at a closed-door lunch.

The AP also reported that most Americans say the war hasn't been worth fighting, per an AP-NORC poll in July. The fighting has already wounded hundreds of American troops.

And this is likely the House's last vote on the war before the midterms. Lawmakers head home this week to campaign.

What the roll call shows

On September 15, 2026, the House voted 220 to 204 to end a war Congress never authorized, and Republicans voted 203 to 7 against it. 180 of the members who voted no have report cards on this site. They cast those votes on the same day Congress's budget office reported the war has cost $38.1 billion so far, is costing $2 billion to $3 billion more each month, and will push inflation higher into 2027. It is the third time since June that the House has voted to end the war, and the third time nearly all of them voted no.
