Four GOP Senators Join Democrats to Rebuke Trump on Iran, Hand Tehran a Talking Point
By Ben SmithFour Senate Republicans handed Democrats a symbolic victory Tuesday, joining them to pass a non-binding war powers resolution rebuking President Donald Trump's handling of the Iran conflict, accomplishing nothing except giving Tehran a headline.
The resolution passed 50-48 with support from Sens. Rand Paul (R-KY), Susan Collins (R-ME), Lisa Murkowski (R-AK), and Bill Cassidy (R-LA). Absences from Sens. Mitch McConnell (R-KY) and Dave McCormick (R-PA) helped secure passage.
The vote followed a similar House rebuke earlier this month, when four Republicans crossed party lines to pass a resolution directing the administration to end hostilities with Iran absent congressional authorization. The House measure passed 215-208.
Neither vote changes a single thing about U.S. policy, and both sides know it.
The Senate action is non-binding and will not go to Trump's desk. Democrats cast the vote as a rebuke of executive war-making authority, but the administration is pressing ahead with Iran negotiations and retains full authority over current policy.
The vote lands as lawmakers are already locked in a more substantive fight over the administration's emerging framework for a longer-term deal with Tehran, one that has stirred real Republican concern over sanctions relief and a proposed reconstruction fund that some in the GOP say goes too far.
After the Senate vote, Trump argued that Congress had handed Tehran a gift at the worst possible moment.

In the post, Trump said Iran had been making significant concessions and accused senators of sending the wrong signal to Tehran.
"So, I have Iran on the 'ropes,' ready to go down for the fall, willing to give us practically anything, and for the first time in decades, respecting the hell out of the United States and its President, ME, and the U.S. Senate decides to have a poorly timed and meaningless War Powers Act Vote, telling the Number One Sponsor of Terror in the World that the United States doesn't like what I am doing to them, and I must stop, and by so doing has provided aid and comfort the Enemy."
The president also singled out the Republicans who voted for the resolution.
"Four Republican Losers voted with the Dumocrats, and Iran asked my people, 'what does that all mean?' These Senators have just made my job more difficult, but I will get it done, one way or the other, because I always get it done! President DJT.”
Republican leaders on Capitol Hill largely opposed the measure.
House Speaker Mike Johnson (LA-04) defended Trump's actions during debate over the House resolution, arguing the administration was responding to a longstanding threat from Tehran.
"Remember … Iran declared war on us 47 years ago. They chant 'death to America.' The president is trying to keep the people safe," Johnson told reporters.
House Foreign Affairs Committee Chairman Brian Mast (FL-21) was even more blunt, dismissing the House vote as political theater.
"I think there's no Democrat, no Republican, that can tell you what forces they would want pulled from Iran. There's really nothing they actually want pulled from there. They just want a stupid political vote, which is what this is," Mast said.
"That weakens the president's hands as he's negotiating with Iran."
Meanwhile, Senate Republicans remain divided over the broader Iran negotiations.
Senate Armed Services Committee Chairman Roger Wicker (R-MS) unloaded on the administration's memorandum of understanding with Iran, warning that it "negotiates away the victories of Operation Epic Fury in ways that are completely out of step with the president's goals.”
That's a serious concern, and a separate fight from Tuesday's symbolic theater.
Other Republicans have flagged concerns over sanctions relief and a proposed reconstruction package tied to any final deal. Senate Majority Leader John Thune (R-SD) made clear that any financial incentives must be conditioned on Iranian compliance with its nuclear commitments, full stop.
Democrats, led by Sen. Tim Kaine (VA), who has built a career on War Powers grandstanding, framed the vote as a constitutional stand for congressional authority.
"If you have to come to us for diplomacy, and you have to come to us for money, you shouldn't be able to end-run us to initiate war on our own," Kaine said.
The resolution he's celebrating, however, is non-binding, goes nowhere near Trump's desk, and does nothing to assert the congressional authority Kaine claims to care about.
The vote does not pull a single troop, touch the Iran negotiations, or alter administration policy by one inch. What it does do is give four Republicans a moment of moral preening, hand Democrats a press release, and send Tehran exactly the kind of mixed signal Trump warned about, right as he claims Iran is closer to a deal than it has been in decades.
