The Senate on Wednesday voted down a measure that would have curbed President Donald Trump's authority to wage the military conflict with Iran, the seventh time the chamber has refused to impose such limits since the war began. The vote failed 50, 49, and the lone Democrat who crossed party lines to help defeat it was Pennsylvania Sen. John Fetterman.
Three Republicans, Lisa Murkowski of Alaska, Susan Collins of Maine, and Rand Paul of Kentucky, broke ranks to vote with Democrats in favor of the resolution. But Fetterman's defection canceled out one of those crossover votes and kept the math squarely on the administration's side.
The result was the first test of Senate sentiment since the 60-day deadline under the War Powers Resolution expired earlier this month. That statutory clock is supposed to force the withdrawal of U.S. forces from hostilities unless Congress grants explicit authorization. Democratic Sen. Jeff Merkley of Oregon introduced the measure, arguing the administration had no legal basis to continue military operations without a vote. The White House disagreed, and enough senators went along to keep the president's hands free.
At the center of the dispute is a straightforward question: did the War Powers Resolution's 60-day limit actually expire, or did the administration find a way around it? Pentagon officials told lawmakers that Operation Epic Fury, the initial combat phase, ended before the 60-day mark. The current phase, they argued, is defined by ceasefire conditions and deterrence rather than active hostilities, and therefore does not require new congressional authorization.
Merkley rejected that reasoning outright. As Spotlight PA reported, the Oregon Democrat told colleagues:
"There's no provision of the law for being suspended. There's no cessation of war activities that would say the war is over."
The Pentagon's position amounts to a claim that relabeling a military operation resets the legal clock, a theory that sits uneasily with the plain text of the statute. But it carried the day. Sen. Josh Hawley of Missouri said Tuesday he was satisfied by the president's declaration that hostilities had been terminated.
"I welcome [the president's] statement that hostilities have been terminated. I think that that satisfies. I think he is now within the bounds of the statute."
Not every Republican was so comfortable. Sen. Mike Rounds said Tuesday that the 60-day clock still applies wherever hostilities or imminent hostilities exist.
"The 60 days apply to areas of hostilities or imminent hostilities. As long as [Iran still has] nuclear weapons materials there, it still applies."
Rounds added that the administration could extend the timeline up to 90 days if needed, but notably, he said he was not backing a new authorization for the use of military force.
The most significant Republican defection came from Murkowski, who voted for the limits for the first time. She had previously warned the administration that she could pursue a formal authorization for use of military force if officials failed to present what she called a credible plan after the war passed the 60-day mark. On Wednesday, she made good on that warning.
AP News reported that three Republicans voted against the war, a sign of growing GOP unease even as the resolution still failed. Murkowski framed her vote as a response to the administration's silence:
"You've got a timeline that has taken us beyond the 60 days. I thought that perhaps we would get beyond that time period, we would get more clarity from the administration in terms of where we are, and I haven't received it."
Before casting her vote, she added that she had urged the White House to work with Congress on a formal AUMF, an authorization for the use of military force, rather than continue operating under executive authority alone.
"I've suggested to the administration it would be helpful if Congress were to move forward with an AUMF."
Collins, the other Republican who voted yes, said her position was nothing new. She told reporters the 60-day trigger in the War Powers Act "is very clear... which is why I voted as I did. But that's not a new position."
The problem for senators who want a formal AUMF is procedural. Unlike war powers resolutions, an AUMF is not privileged, meaning it is likely to remain stuck in committee rather than reach the floor for a vote.
Fetterman's vote against the measure placed him on the same side as Trump and the vast majority of Senate Republicans. No quotes from Fetterman explaining his reasoning appeared in the available reporting, but his vote is consistent with a pattern that has made him one of the most unpredictable members of the Democratic caucus.
The Pennsylvania senator has repeatedly rebuked his own party on issues ranging from foreign policy to domestic culture fights, earning him praise from the right and fury from the left.
His willingness to side with the administration on the Iran conflict is especially striking given how aggressively Democrats have tried to make war powers the wedge issue of the session. Sen. Tim Kaine of Virginia framed Wednesday's vote as a loyalty test before it was cast:
"Today is the first test of their fidelity to the principle that they have laid down."
Kaine was talking about Republicans who had previously expressed concern about the war's legal footing. But Fetterman's vote made clear that the fidelity problem runs in both directions. Democrats could not hold their own caucus together on the question.
Trump has taken notice of Fetterman's independent streak. The president has dangled endorsement and fundraising support to try to lure the senator into the Republican Party, an offer Fetterman has so far declined, even as his voting record continues to diverge from Democratic leadership on high-profile issues.
Meanwhile, the military footprint in the region has not shrunk. U.S. forces remain deployed, a blockade of Iranian ports remains in place, and the Pentagon recently launched an operation in the Strait of Hormuz dubbed Project Freedom. Maritime tensions continue in surrounding waters, with intermittent exchanges involving Iranian and U.S. forces.
Defense Secretary Pete Hegseth told lawmakers Tuesday that the administration believes it retains full authority to resume strikes if the ceasefire collapses. He cited the president's powers under Article II of the Constitution.
"Our view is that should the president make the decision recommence, that we would have all the authorities necessary to do so."
The Pentagon is reportedly considering the name Operation Sledgehammer if strikes resume, a detail that underscores how far planners have already gone in preparing for a return to active combat.
Republican Sen. John Curtis has previously said he would not support continued funding for military operations without Congress being directly involved. Whether that position holds under pressure from party leadership remains an open question.
Fetterman has also drawn attention for blaming what he called "TDS" for Democratic opposition to unrelated White House matters, a rhetorical choice that further distances him from his caucus.
Seven failed votes in a row tell a clear story: the Senate does not have the will to constrain the president's war-making authority in Iran. The War Powers Resolution was written to prevent exactly this kind of drift, an open-ended military commitment sustained by executive fiat while Congress holds symbolic votes and loses every time.
The administration's argument that relabeling a military operation resets the legal clock is creative lawyering, and it may even be correct in a narrow technical sense. But the broader reality is that U.S. forces remain in theater, a naval blockade is active, and the Pentagon has a name picked out for the next round of airstrikes. If that does not constitute the kind of situation the War Powers Resolution was designed to address, it is hard to imagine what would.
Fetterman's vote matters not because it changed the outcome, the resolution would have failed regardless, but because it deepens the fracture inside a Democratic Party that cannot even unify on the question of whether a sitting president should have to ask Congress before waging war. That used to be a principle Democrats claimed to care about more than anyone.
Kaine warned that a day would come, "and it might be soon", when the Senate tells the president to stop the war. Seven votes later, that day keeps not arriving. And the senator from Pennsylvania keeps making sure it doesn't.
