Senate Rejects Democratic Bid to Rein In Trump’s War Powers on Iran

The Senate on Wednesday rejected a Democratic-led effort to rein in President Donald Trump’s authority to wage war against Iran, the fourth time this year that lawmakers have voted down a War Powers measure aimed at forcing Congress to authorize the conflict.

The resolution failed on a 52–47 vote, with most Republicans lined up against it and all but one Democrat in support. Sen. Rand Paul, Republican of Kentucky, broke with his party to back the measure. Sen. John Fetterman, Democrat of Pennsylvania, sided with Republicans and opposed it. Sen. Jim Justice, Republican of West Virginia, did not vote.

The resolution sought to invoke the War Powers Resolution of 1973 to compel the administration to withdraw U.S. forces from “hostilities” with Iran unless and until Congress formally approved the campaign through a declaration of war or a specific authorization for the use of military force.

Democrats led by Sen. Cory Booker of New Jersey, Sen. Tim Kaine of Virginia, Sen. Chris Murphy of Connecticut and their allies framed the vote as a bid to halt what they describe as Trump’s “war of choice” with Iran until Congress can debate and vote on it. Rep. Adam Schiff of California has been a principal ally in the House.

Senate Majority Leader Chuck Schumer, a New York Democrat, urged Republicans before the vote to join Democrats in curbing the operation. “The American people literally cannot afford for Republicans to forgo another opportunity to work with Democrats to end Trump’s disastrous war,” Schumer said.

The latest clash comes as the clock ticks toward a May 1 deadline under the War Powers statute, which generally requires presidents to end unauthorized hostilities after 60 days unless Congress signs off. News reports have noted that the current U.S. operation against Iran, launched in late February in coordination with Israel, is approaching that cutoff.

Under the War Powers Resolution of 1973, the president must notify Congress within 48 hours of introducing U.S. forces into hostilities or into situations where hostilities appear imminent. The law then gives a 60‑day window for military action without explicit congressional authorization, after which forces are supposed to be withdrawn unless Congress declares war, passes a specific authorization or extends the period.

With U.S. forces engaged in major operations against Iran and reports of American service members killed in the region, Democrats have repeatedly forced votes to test support for Trump’s approach. They argue that the Constitution gives Congress, not the president alone, the authority to decide on war.

Republicans have largely backed the president’s strategy, warning that cutting off authority in the middle of combat could embolden Iran and undermine U.S. credibility. But the votes and public statements have exposed some unease inside the GOP over the lack of a clear endgame or fresh authorization from Congress.

Sen. Susan Collins, Republican of Maine, who has criticized aspects of Trump’s approach while opposing the Democratic resolution, underscored that concern. “I have been clear from the beginning of this military operation that the President’s power is not unlimited as Commander in Chief, as the Constitution gives Congress an essential role in matters of war and peace,” Collins said.

Other Republicans, including Senate Majority Leader John Thune of South Dakota and Sens. Lisa Murkowski of Alaska, Thom Tillis of North Carolina and John Curtis of Utah, have signaled through recent comments reported by news outlets that they want a clearer plan for the Iran campaign. Some have indicated that Congress should formally authorize the operation if it continues past the War Powers deadline.

The White House has defended Trump’s approach as tough but necessary, saying the military pressure on Iran is meant to force Tehran to accept U.S. demands on its nuclear program. Anna Kelly, a White House spokeswoman, said the president prefers negotiations but will not ease up absent concrete concessions.

“The President’s preference is always diplomacy, and Iran is desperate to make a deal — but they first must renounce their desire for a nuclear weapon and agree to redlines articulated by the United States,” Kelly said.

The fight with Iran, and the regional instability surrounding it, has been tied in news reports to higher gas prices and broader economic strain in the United States. Democrats have cited those pressures, along with U.S. casualties, in arguing that Congress should more aggressively check the president’s war powers.

Wednesday’s vote followed three earlier failed Senate attempts this year to advance Iran-related War Powers resolutions. On March 4, senators rejected a motion to move forward on a measure from Kaine by a 47–53 margin. A similar Democratic-led effort associated with Booker and his allies was defeated 47–53 on March 18. On March 24, another resolution backed by Murphy, Schiff, Booker and others was blocked, 53–47.

Together, the four roll calls have created a steady record of where senators stand on Trump’s Iran policy ahead of the May 1 War Powers deadline. While none of the measures has passed, each has drawn at least one Republican vote, reflecting a small but persistent faction in the president’s party that is uncomfortable with an open‑ended conflict absent explicit congressional authorization.

For now, the rejected resolutions leave Trump’s military campaign against Iran continuing under his existing claim of authority, even as lawmakers in both parties debate how long that can last without Congress taking clearer ownership of the war.
