Congress took dueling votes on Thursday over President Donald Trump's authority to wage war against Iran, with the House narrowly approving a non-binding resolution to end hostilities while the Senate rejected a legally binding version. The split outcome reflects growing bipartisan skepticism on Capitol Hill about the conflict, even as some Republicans urge Trump to intensify military action. The votes, pushed by Democrats ahead of the November midterms, mark the first major test of Republican support for the renewed strikes against Tehran this month, according to The Washington Post.

Main Story

The House on Thursday voted 214-208 to approve a Democratic-led war powers resolution directing President Donald Trump to remove U.S. armed forces from hostilities with Iran. The measure is non-binding, meaning it does not carry the force of law, but it represents a clear congressional rebuke of the administration's handling of the conflict. Four Republicans crossed party lines to support the resolution: Reps. Thomas Massie of Kentucky, Tom Barrett of Michigan, Warren Davidson of Ohio, and Brian Fitzpatrick of Pennsylvania. All House Democrats voted in favor, according to NBC News.

Later in the day, the Senate voted 47-49 to reject a joint resolution that would have the force of law, requiring Trump to seek congressional authorization for the war. Unlike the House version, a joint resolution is subject to a presidential veto. The Senate measure fell short of the 60 votes needed to advance, with only one Republican, Sen. Susan Collins of Maine, joining all Democrats except Sen. John Fetterman of Pennsylvania. Four Senate Republicans did not vote: Sens. Katie Britt of Alabama, Mitch McConnell of Kentucky, Lisa Murkowski of Alaska, and Rand Paul of Kentucky, as reported by NBC News.

The votes mark the first test of Republican support for the conflict since President Trump resumed military strikes against Iran earlier this month, according to The Washington Post. This is also the second time the House has approved a similar resolution rebuking Trump on Iran war powers, as noted by The New York Times.

Why It Matters

The dueling votes underscore a deepening divide in Congress over the U.S. military campaign against Iran. While President Trump has threatened to intensify the war and some Republican lawmakers urge him to finish the job, there is widespread skepticism on both sides of the aisle about whether the administration can deliver a clear victory, according to The Hill. The non-binding House resolution serves as a symbolic but significant statement of congressional opposition, while the Senate's rejection of a binding measure leaves the president with a free hand to continue military operations.

The votes also highlight Congress's ongoing struggle to reassert its constitutional authority to declare war. Democrats have pushed these measures to force Republicans to go on the record about an unpopular war ahead of the November midterm elections, as reported by NBC News.

Political Context

The war with Iran has become a central issue in the 2026 midterm campaign. Democrats are eager to tie Republican incumbents to a conflict that polls show is unpopular with voters. By forcing votes on war powers resolutions, they aim to create a clear contrast: Democrats voting to end the war, while most Republicans vote to continue it. The four House Republicans who broke ranks — Massie, Barrett, Davidson, and Fitzpatrick — represent a mix of conservative and swing districts, suggesting that the issue cuts across party lines.

In the Senate, several Republicans have expressed concerns about the war's duration. Sens. Thom Tillis of North Carolina and John Curtis of Utah have stated that the conflict should not go beyond 60 days without congressional approval to comply with federal law. Yet both voted against the joint resolution on Thursday, illustrating the political pressure to support the president, according to NBC News.

What Officials and Groups Are Saying

President Trump has threatened to intensify the war with Iran, and some Republican lawmakers have urged him to finish the job. However, there is widespread skepticism on Capitol Hill about the prospects for a clear victory, according to The Hill. The White House has not commented directly on the House vote, but press secretary Karoline Leavitt reiterated the administration's position on a related matter, linking a Saudi normalization deal to progress on the Abraham Accords.

Democratic leaders hailed the House vote as a necessary step to reassert Congress's war powers and hold the administration accountable. Republicans who supported the measure argued that the Constitution requires congressional authorization for prolonged military engagements. Opponents, including most Senate Republicans, maintained that the president needs flexibility to conduct foreign policy and that binding resolutions would undermine national security.

Timeline

  • Mid-July 2026: Growing casualties and public unease prompt Democratic leaders to schedule war powers votes.
  • July 23, 2026: House votes 214-208 to approve non-binding war powers resolution; Senate votes 47-49 to reject binding joint resolution.
  • Next steps: The House resolution has no legal force; the Senate's rejection leaves Trump free to continue operations. Democrats plan to keep the issue in the spotlight ahead of November's elections.
