The Trump administration told Congress on Friday that the war with Iran is over, on paper, at least, just as the 60-day clock under the War Powers Resolution ran out. In a letter addressed to House Speaker Mike Johnson and Senate President Pro Tempore Chuck Grassley, President Trump declared that "the hostilities that began on February 28, 2026, have terminated," a move that lets the White House sidestep a legal requirement to seek congressional authorization for continued military action.
The timing was not subtle. Friday was the final day of the 60-day window the 1973 War Powers Resolution gives a president to either obtain Congress's blessing or withdraw forces after committing them to hostilities abroad. Rather than ask lawmakers to vote, the administration chose a different path: declare the fighting finished and argue the deadline no longer applies.
Whether that argument holds up, legally, politically, or practically, is now the central question in Washington. And Congress, which left town Thursday for a weeklong recess without lifting a finger to enforce its own authority, has no one to blame but itself.
Defense Secretary Pete Hegseth previewed the White House position during a congressional hearing Thursday, telling senators that the early-April ceasefire between the U.S. and Iran effectively froze the war-powers clock. Breitbart reported that Hegseth's remarks reinforced the administration's broader legal argument that no further authorization was needed.
Hegseth put it plainly:
"We are in a ceasefire right now, which our understanding means, the 60-day clock pauses or stops."
Trump echoed that position Friday at the White House before departing for Florida. He went further, questioning the constitutionality of the War Powers Resolution itself, a complaint shared by presidents of both parties going back decades.
"Every other president considered it totally unconstitutional, and we agree with that."
That framing is not new. Presidents from Nixon onward have bristled at the 1973 law. But the specific claim here, that a ceasefire "terminates" hostilities for purposes of the statute, even while U.S. forces remain deployed and the Navy maintains a blockade in the Strait of Hormuz, is a novel interpretation. The Washington Times noted that legal experts and some lawmakers say the administration's argument that the clock paused or ended lacks legal support.
Trump's letter acknowledged the tension between declaring the war over and keeping forces in the region. It stated that "despite the success of United States operations against the Iranian regime and continued efforts to secure a lasting peace, the threat posed by Iran to the United States and our Armed Forces remains significant." That is a remarkable admission: the threat is significant, but the hostilities are terminated.
The more revealing story may not be the White House's legal maneuvering. It may be Congress's refusal to act. The Senate rejected a Democratic attempt to halt the war for a sixth time before lawmakers scattered for recess. Senate Majority Leader John Thune said Thursday he saw no path to a vote authorizing force in Iran.
"I'm listening carefully to what the members of our conference are saying, and at this point I don't see that."
Thune did suggest the White House should step up its outreach, calling for more regular briefings from military leadership. But a suggestion for more briefings is a far cry from exercising the constitutional power to declare war, or to deny authorization for one.
That passivity is not unique to this moment. A similar pattern played out during the 76-day DHS funding standoff, where Congress delayed action until the last possible moment before resolving a crisis of its own making.
Some Republican senators, however, are not content to sit quietly. Maine Sen. Susan Collins voted with Democrats on Thursday to halt the war, her first time crossing the aisle on the issue. She was direct about what the law requires:
"The president's authority as commander in chief is not without limits."
Collins added that the War Powers Resolution's requirement for congressional authorization is "not a suggestion, it is a requirement."
Collins is not alone. Utah Sen. John Curtis said he would not support continued funding for the war until Congress votes to authorize it. Newsmax reported that GOP leaders are declining to force such a vote even as the deadline arrived and U.S. military pressure on Iran continues.
Curtis framed it as a matter of institutional cooperation, not confrontation:
"It is time for decision-making from both the administration and from Congress, and that can happen in league with one another, not in conflict."
Indiana Sen. Todd Young struck a similar tone. He said lawmakers "must ensure that the people, through their elected representatives, weigh in on whether to send our military into combat." Young accepted the administration's claim that the conflict has ceased but added a condition: if hostilities resume, he expects the White House to work with Congress to pass an authorization for use of military force.
North Carolina Sen. Thom Tillis, Alaska Sen. Lisa Murkowski, and Missouri Sen. Josh Hawley all said they would eventually like to see a vote, a position that falls somewhere between demanding action and accepting the status quo. North Dakota Sen. Kevin Cramer, meanwhile, offered a more deferential view of executive power.
"Our founders created a really strong executive, like it or not like it."
That range of opinion within the Republican conference, from Collins's insistence on the law's requirements to Cramer's deference to the executive, illustrates why Thune sees no path to a vote. The caucus is split, and the easier political choice is to let the president carry the weight of the decision.
It's a pattern that extends well beyond war powers. Recent clashes between Republican senators and the administration over FCC pressure on broadcasters show the same dynamic: individual members voice concern, but the institution as a whole declines to act.
Democrats, predictably, are furious. Connecticut Sen. Richard Blumenthal wrote on social media that the administration's ceasefire theory has no basis in law:
"There's no pause button in the Constitution, or the War Powers Act. We're at war. We've been at war for 60 days. The blockade alone is a continuing act of war."
Blumenthal's point about the blockade is worth weighing. The U.S. Navy is maintaining a presence in the Strait of Hormuz to prevent Iranian oil tankers from reaching open water. Iran, for its part, maintains its own chokehold on the strait. Whether a naval blockade counts as "hostilities" under the War Powers Resolution is a legal question that the administration clearly wants to avoid answering.
Rep. Adam Smith of Washington, the ranking Democrat on the House Armed Services Committee, offered an even blunter assessment to the Associated Press:
"Is the expectation that the Trump administration is going to follow the law? I do not have that expectation."
Smith's remark reveals more about Democratic strategy than he may intend. If Democrats genuinely believe the law is being violated, the remedy is legislative action, not a quote to a wire service. They have tried six times in the Senate to halt the war and failed each time. The votes are not there.
And that failure is not solely a Republican problem. The broader pattern of legislation moving to Trump's desk shows a Congress that can act when it wants to. On Iran, it has chosen not to.
The administration's entire legal position rests on the ceasefire that began in early April. Trump initially said the war would last a few weeks. The ceasefire, described in the Associated Press's reporting as "shaky," arrived roughly five weeks into the conflict. No U.S.-Iran fire has been exchanged since, but U.S. forces remain in the region and the naval blockade continues.
The open questions are significant. What happens if the ceasefire collapses? Does the 60-day clock restart from zero, or does it pick up where it left off? The administration has not said. Todd Young's conditional support, he expects the White House to seek authorization if fighting resumes, suggests at least some Republicans would demand a vote in that scenario.
But that is a promise for the future. Right now, the president has declared the war over, Congress has left town, and American ships remain on station in one of the world's most volatile waterways.
The administration has shown a willingness to make consequential moves at speed, and this is no exception. The letter to Johnson and Grassley landed on the last possible day, with the maximum legal exposure and the minimum political resistance.
The War Powers Resolution exists because Congress wanted to prevent presidents from waging open-ended wars without democratic accountability. Every president since Nixon has treated the law as an inconvenience. Trump is no different in that regard. But the law's weakness is not just executive defiance, it is legislative cowardice. Congress has the power to authorize or deny the use of force. It has the power to cut funding. It has the power to hold hearings, compel testimony, and force votes.
Instead, it left town.
The Constitution gives Congress the power to declare war. If lawmakers won't use it, won't even vote on it, they have no standing to complain when a president fills the vacuum they created. The administration's legal theory may be creative. But a Congress that won't show up for its own deadlines has already conceded the argument.
