Ohio – Former President Donald Trump is celebrating a dramatic turnaround in the Senate after Republicans blocked another effort to limit his authority over military action involving Iran. The late-night vote came just one day after a similar resolution had passed, marking a sharp reversal that Trump quickly hailed as a major victory while publicly recognizing Ohio Senator Bernie Moreno for helping rally Republican support.
On Truth Social, Trump highlighted the outcome and thanked several GOP lawmakers by name.
“Wow! The Senate just changed its vote on Iran from 50-48 against, to 50-47 for. Rand Paul and Bill Cassidy changed. Thank you to Leader John Thune, Lindsey Graham, Bernie Moreno, and all. This vote puts Iran on notice! President DJT”
The president’s message came after days of frustration over Republican defections on Iran policy. Earlier in the week, Trump had sharply criticized members of his own party who supported a war powers resolution, accusing them of making his diplomatic efforts more difficult. He even labeled the Republican senators who backed Tuesday’s measure as “losers,” arguing their votes weakened America’s negotiating position with Iran.
Republicans reverse course after tense White House discussions
The Senate’s latest vote represented a major shift from the previous day.
On Tuesday, senators approved a resolution intended to limit the president’s authority over military operations involving Iran. By Wednesday night, however, Republicans successfully defeated another attempt to move forward with a similar measure.
The final vote ended 50-47, with one senator voting present.
A key reason for the different outcome was the change in position taken by two Republican senators.
Kentucky Senator Rand Paul, who had previously supported limiting presidential war powers, chose to vote present instead. Louisiana Senator Bill Cassidy also switched sides, voting against advancing the resolution after initially backing similar legislation.
Two Republicans, Susan Collins of Maine and Lisa Murkowski of Alaska, again voted in favor of the war powers measure. Democratic Senator John Fetterman once again broke with most members of his party by voting against it.
The late-night reversal followed a tense closed-door lunch between Trump and Senate Republicans earlier that day.
Cassidy later described a direct exchange with the president, saying he had challenged the administration over the conflict.
“I stood and said, ‘You have not told the American people what’s going on. It was supposed to last four weeks, it’s lasted four months. Our original objectives have not been achieved, and I want to know what’s going on,” Cassidy told reporters after the meeting.
Later in the day, however, Cassidy said additional information from senior administration officials addressed many of the concerns he had raised. “I want to thank Vice President Vance and Special Envoy Witkoff for the thorough briefing this afternoon on Iran. I appreciate the quick invitation to the White House to address many of my concerns,” he wrote on X.

Rand Paul also explained why he altered his vote despite maintaining his long-standing position on congressional authority over military action.
“My opinion on the debate over war and executive power has not changed and I have voted that way several times. But since hostilities seem to be over and the President asked me to give consideration to his negotiating position, I will do so. My vote of present is a way to give the President more space and leverage to negotiate a lasting peace,” he posted.
Tonight I will vote present on the War Powers resolution.

Trump intensifies pressure on Republicans
Trump has repeatedly argued that congressional efforts to restrict presidential military authority send the wrong message during sensitive international negotiations.
After Tuesday’s Senate vote, he lashed out at the four Republican senators who sided with Democrats, saying, “These Senators have just made my job more difficult.”
Earlier this month, after several House Republicans also voted with Democrats on a related resolution, Trump criticized them as “GRANDSTANDERS” and called their actions “unpatriotic.”
During Wednesday’s Republican lunch, Trump also expressed frustration with senators who missed Tuesday’s vote altogether, including Dave McCormick and Mitch McConnell. McConnell remains hospitalized, while McCormick was traveling aboard Air Force One with Trump during the earlier vote.
Wednesday’s vote marked the eleventh time the Senate has considered an Iran war powers measure since the beginning of the year. Democrats had delayed bringing the latest version back to the floor until they believed they had enough support, while Republicans saw an opportunity to defeat it after attendance patterns shifted.
Supporters of the legislation argue Congress should have a direct role before the United States becomes involved in another military conflict.
Virginia Democratic Senator Tim Kaine has been among the leading advocates for the proposal, maintaining that lawmakers should formally weigh in even after a preliminary agreement with Iran appeared to reduce immediate tensions.
“I think it’s a good time to have the vote to say, ‘Hey, if we’re really in a period of maybe some stability here, let’s not just allow it to start up again without Congress being involved in that decision,” he said last week.
For Trump, however, Wednesday night’s outcome represented more than just another Senate vote. After publicly criticizing Republicans who opposed him only a day earlier, he celebrated the reversal as proof that his administration had regained momentum on one of its most closely watched foreign policy battles. In doing so, he singled out Bernie Moreno alongside Senate Majority Leader John Thune, Lindsey Graham, and other Republicans whom he credited with helping deliver what he viewed as a significant political and diplomatic victory.
