Senate votes – With Trump warning he could resume bombing Iran, the Senate voted 50-48 to order the president to withdraw U.S. forces from Iran unless Congress authorizes further war—marking another bipartisan rebuke after a symbolic House vote earlier this month.
For the second day in a row, the Senate’s chamber felt like a pressure valve—and it came with a deadline embedded in the vote.
On Tuesday, the Senate voted 50-48 on a resolution ordering the president to pull U.S. forces out of Iran pending the legislative branch actually authorizing the war. The message was clear even if the legal impact was limited: the resolution is not binding. but it sends a direct bipartisan signal that Congress is drawing a line on the president’s Iran conflict.
The vote also split Republicans in a way that undercut any attempt to portray the measure as purely partisan. Four Republican senators—Susan Collins of Maine, Lisa Murkowski of Alaska, Rand Paul of Kentucky, and Bill Cassidy of Louisiana—broke with their party to vote in favor of the resolution.
As lawmakers moved toward the tally, Sen. Chris Van Hollen, a Democrat from Maryland, told the Senate, “We should take a stand today and end this war, and we should finally start putting the interests of the American people ahead of costly and unnecessary conflicts.”
Earlier this month, the House passed a similar measure aimed at ending the war. That vote matters because, according to the resolution’s supporters, the conflict was unilaterally started by the president in February without Congress’s authorization.
In the House, Democrats joined Republican Reps. Thomas Massie of Kentucky, Brian Fitzpatrick of Pennsylvania, Tom Barrett of Michigan, and Warren Davidson of Ohio in passing their own symbolic resolution condemning the war.
The pattern has been building: first, a House rebuke through a nonbinding resolution; then, another bipartisan vote in the Senate with the same core demand—withdraw forces unless Congress authorizes the war.
Yet the stakes are complicated by how quickly the White House has signaled it could ignore that pressure. Trump has continued to threaten to reignite the conflict and undermine the effort to finalize a peace deal with Iran, even as the Senate tried to turn its displeasure into a concrete order.
Around the same time as the Senate vote. Trump declared at an event in Pennsylvania that “the only thing they understand is the hammer. ” a reference to Iran. Days earlier. on Sunday. Trump used Truth Social to warn that if Lebanon did not cease military skirmishes with Israel—fighting that has been unfolding since the beginning of the Israel-Gaza war and escalated in the aftermath of Trump’s Iranian offensive—he would “hit Iran very hard again. just like we did last week. only harder!!!”.
The contradiction is hard to miss. Congress can wag its finger, vote to demand withdrawal, and force the president to face another public clash over war powers—but in the end, the resolution can’t force specific actions.
So for lawmakers, the fight is not just about Iran. It’s about whether the president’s next move will be shaped by the legislative branch’s refusal to sign off on continued war—especially when the president has repeatedly made threats that suggest compliance is optional.
