Senate votes to end Iran hostilities in rare rebuke
The Senate voted 50-48 to approve a resolution directing President Trump to withdraw U.S. forces from Iran, marking the first such rebuke since 1973. Four Republican senators joined Democrats in passing the measure, which does not require the president's signature. The White House dismissed the vote as legally insignificant, arguing hostilities ended in April.

The Senate approved a House-passed resolution Tuesday directing President Donald Trump to withdraw U.S. armed forces from hostilities against Iran, after four Republican senators broke ranks in a rare vote to undercut the president’s commander-in-chief authority. The Senate voted 50-48 to approve the measure, while the House passed it earlier this month by a vote of 215-208. This marked the first time both chambers had approved a resolution directing a president to remove U.S. forces from hostilities since Congress enacted the War Powers Resolution in 1973.
The measure came straight to the Senate floor for an up-or-down vote and does not require Trump’s signature because it is a concurrent resolution. Under the 1973 law, Congress intended such resolutions to end military operations, but legal experts say the issue remains unsettled. No war powers resolution had previously passed both chambers, and a 1983 Supreme Court ruling said such a measure must go to the president for signature or veto to have legal effect.
The White House has argued that the War Powers Act is unconstitutional and not binding. A White House official told Reuters the vote had no significance because the resolution does not go to Trump and carries no force of law. The official also stated that hostilities ended with an April 7 ceasefire.
Sens. Rand Paul (R-Ky.), Susan Collins (R-Maine), Lisa Murkowski (R-Alaska) and Bill Cassidy (R-La.) voted with Democrats. Sen. John Fetterman (D-Pa.) was the only Democrat to vote against the resolution. Sen. Bernie Sanders (I-Vt.) welcomed the vote, saying Congress had finally asserted its constitutional role over war powers. "Congress finally did what should have been done months ago: voted to demand Trump end his war with Iran," Sanders wrote on X.
The symbolic setback comes as the administration is expected to seek tens of billions of dollars for the war. A Reuters/Ipsos poll released Tuesday found that only about one in four Americans believe the Iran war was worth its costs. The Trump administration is currently trying to negotiate a peace agreement with Iran, and Congressional support for the resolution is likely to increase pressure on Trump not to resume attacks if negotiations falter.
How will this congressional pressure impact the administration's leverage at the negotiating table with Iran?
Could the Republican defections signal a broader shift in the party's stance on foreign intervention ahead of the next election cycle?
What legal challenges might arise if the administration ignores the resolution and resumes military hostilities?
