House Votes to Limit Trump War Powers as Senate Balks

The House of Representatives voted again to rein in President Donald Trump's military campaign against Iran, passing a war powers resolution that directs the president to end U.S. hostilities unless he receives explicit authorization from Congress. Four Republicans crossed the aisle to join Democrats in a rebuke that lays bare the deep unease on Capitol Hill over a conflict that has now stretched on for nearly two weeks.
The measure passed the House but ran into a wall in the Senate, where a parallel resolution to withdraw U.S. troops from Iran narrowly failed after Republican leaders blocked it from advancing. The split outcome leaves Congress at an impasse: one chamber demanding limits on the war, the other unable or unwilling to follow suit, and a president determined to press ahead.
At the heart of the fight is the War Powers Resolution of 1973, a post-Vietnam law that requires the president to seek congressional approval for sustained military action. Lawmakers backing the resolution argue that Trump has committed U.S. forces to open-ended combat against Iran without the constitutionally required authorization, and that Congress must reassert its role as the branch empowered to declare war.
The human cost has sharpened the debate. Nearly 100 U.S. service members have been injured since hostilities with Iran resumed, and the American death toll now stands at 18. Iranian missiles have struck U.S. military targets across the region in retaliation for American strikes, and each new casualty has intensified pressure on lawmakers to define the limits of the campaign.
The four Republicans who joined Democrats in the House reflect a small but vocal faction of the president's own party that has grown wary of another prolonged Middle East war. Their votes were not enough to override a presidential veto, but they signaled a crack in the wall of partisan support and gave the resolution a bipartisan imprimatur its backers were eager to claim.
For his part, Trump has shown no sign of backing down. He told Axios he is weighing whether to restart major combat operations in Iran, including strikes larger than those carried out during what the administration dubbed 'Operation Epic Fury,' though he stressed no final decision had been made. Iran, meanwhile, has rejected a ceasefire proposal that was relayed through Iraq's prime minister.
The standoff exposes an enduring tension in the American system over who controls the use of military force. Presidents of both parties have for decades stretched their authority to deploy troops without formal declarations of war, and Congress has repeatedly struggled to claw that power back. The current showdown is the latest chapter in a constitutional argument as old as the republic itself.
Even if the House resolution had cleared both chambers, it would almost certainly have faced a presidential veto, and supporters lack the two-thirds majorities needed to override one. That reality has led critics to dismiss the vote as symbolic. Backers counter that forcing lawmakers to go on record — and building a bipartisan coalition — is itself meaningful, laying groundwork for future action and public accountability.
The Senate's failure to pass its own measure underscored the political calculations at play. Republican leaders, reluctant to hand the president a public defeat during an active conflict, used procedural tools to keep the resolution from a decisive vote. Democrats accused them of abdicating Congress's constitutional duty, while Republicans framed their stance as support for the commander in chief in wartime.
The conflict itself shows little sign of cooling. U.S. forces have carried out repeated rounds of strikes, and Iranian retaliation has spread across the region, raising fears of a wider war. Oil markets have swung sharply on the news, with prices surging past $100 a barrel earlier in the week amid attacks on Red Sea shipping before easing somewhat.
What comes next remains uncertain. The House vote keeps the war powers question alive and guarantees continued political friction as the conflict grinds on. With Trump signaling he may escalate and Congress divided over how to respond, the coming days could prove decisive — both for the trajectory of the war and for the long-running struggle over who holds the power to wage it.
