U.S. House Passes War Powers Resolution to End Iran Conflict in Third Legislative Push

POLICY WIRE — Washington, United States — For a third time, the U.S. House has voted to end the war in Iran, approving a war powers resolution that would halt President Donald Trump’s ability to continue military action without congressional approval.

The roll call late Tuesday resulted in a 220-204 vote, closely mirroring earlier legislative efforts from the summer. A small group of additional Republicans joined all participating Democrats to support bringing an end to the ongoing conflict. None of the prior resolutions have reached the president’s desk, and Trump would almost certainly veto the measure.

Remember when Donald Trump said that this war would last just a few weeks?, asked Rep. Seth Moulton, D-Mass., a former Marine who served during the Iraq War and helped drive the resolution forward.

Moulton argued that it is time for Congress to actually ask tough questions, as the Constitution directs us to do, rather than be subservient to another warmongering administration.

On the opposing side, Republican Rep. Brian Mast of Florida, who serves as the chairman of the House Foreign Affairs Committee, questioned which military resources Democrats intended to withdraw from a region where he argued Iran remains an active threat.

Mast maintained that Trump is against forever wars, and that is what he is ending by tackling decades of hostilities stemming from Iran. They are a continuous ongoing threat to the United States, Mast added. Enough is enough.

The legislative action is widely expected to be the final House vote concerning the Iran war prior to the midterm elections. The overseas conflict has taken a prominent role in domestic political campaigns following the war’s launch by Trump on Feb. 28, which has dragged on with recurring, deadly missile exchanges and regional disruption for nearly seven months.

Lawmakers are preparing to leave Washington at the end of the week to focus on full-time campaigning. With less than 50 days remaining before elections that will dictate control of Congress, Democrats are aggressively trying to wrest power away from Republicans.

Voters across the country are facing heightened financial pressures, particularly driven by high prices at gas pumps as the military conflict continues to disrupt vital oil shipments moving through the Strait of Hormuz.

According to a Congressional Budget Office report released Tuesday, the war has accumulated costs exceeding $38 billion as of Aug. 1. The agency projects ongoing monthly expenditures between $2 billion and $3 billion, depending heavily on the intensity of combat operations. Furthermore, the budget office estimated that inflation will rise 0.5 percentage points higher than originally anticipated heading into 2027 as a direct result of the war.

President Trump initially pledged to keep the United States out of foreign military engagements when securing his second term in the White House. However, his actions involving Iran continue to weigh heavily on the Republican Party, which maintains majorities in both the House and Senate. An AP-NORC poll conducted in July indicated that a majority of Americans believe the war in Iran has not been worth fighting.

While previous House measures saw only four Republicans cross party lines to support halting the war, Tuesday’s vote saw that figure climb to seven lawmakers. The expanded bipartisan group included GOP representatives from competitive battleground districts in Iowa, Rep. Zachary Nunn and Rep. Mariannette Miller-Meeks, alongside retiring Rep. Nancy Mace of South Carolina.

These representatives joined Republican Reps. Tom Barrett of Michigan, Warren Davidson of Ohio, Brian Fitzpatrick of Pennsylvania, and Rep. Thomas Massie of Kentucky, who voted alongside all voting Democrats in favor of the resolution.

Despite repeated attempts by Congress to alter the strategic direction of the campaign against Iran, passing measures to successfully curb the Trump administration’s military authority remains a steep challenge as long as the executive branch retains veto power.

The House initially approved a war powers resolution in June, followed by a second attempt in July, both aimed at halting U.S. military engagement in Iran. In the Senate, a war powers resolution passed on its 10th try, though GOP senators rapidly reversed their positions the following day after facing criticism from Trump during a closed-door lunch meeting.

Although the U.S. Constitution grants Congress the formal power to declare war, it also establishes the president as commander in chief with independent authority over certain military operations. The War Powers Act, enacted in the wake of the Vietnam conflict, was designed to introduce strict time limitations on presidential authority, mandating explicit congressional authorization for sustained military campaigns lasting beyond 60 or 90 days.

House Speaker Mike Johnson asserted his belief that the Iran conflict is transitioning into a new phase as international allies increase their support to help stabilize the region. When that stabilization occurs, Johnson suggested, gas prices will drop, subsequently lowering the cost of everyday groceries.

Johnson noted that Trump anticipates this economic shift following the election, adding, I’d love it to happen today.
