Executive Summary
The war in Iran reaches the 60-day mark on May 1 under the War Powers Resolution, triggering a critical constitutional deadline. Under the law, the president is required to give formal notification to Congress within 48 hours of introducing American forces into hostilities, which officially begins a 60-day clock for the president to terminate the use of force unless Congress has declared war or authorized the use of military force.
Defense Secretary Pete Hegseth told senators that "We are in a ceasefire right now, which our understanding means the 60-day clock pauses or stops". This assertion represents a novel legal interpretation that contradicts the statutory text and faces strong opposition from legal experts and Democratic lawmakers. The War Powers Resolution "is not something that by its text or by its design the War Powers Resolution accommodates," according to Katherine Yon Ebright of the Brennan Center.

- The 60-Day Deadline is Legally Binding
The Trump Administration formally notified Congress of its military campaign on March 2, triggering the clock that expires Friday. Absent congressional authorization or a withdrawal certification, many legal scholars and lawmakers argue that the U.S. will be violating federal law if it continues military action in Iran after Friday.
- The Ceasefire-Pause Argument Lacks Statutory Support
Democratic lawmakers and legal experts argue that the statute contains no provision allowing for a pause once the deadline has started. Bruce Fein, a US constitutional and international law expert and former associate deputy attorney general, said the resolution "never says anywhere" that the 60-day deadline "stops if there's a ceasefire," warning that such an interpretation "turns the resolution into simply a paper tiger".
- Ongoing Hostilities Undermine the Ceasefire Claim
Despite a halt in air and missile strikes, US and Iranian forces have continued hostilities in and around the Strait of Hormuz. On April 20, the US military fired on and seized the Iranian‑flagged container ship Touska, with Tehran days later capturing two foreign commercial vessels. Trump has responded to the Islamic Republic's effective seizure of the Strait of Hormuz, a chokepoint through which a fifth of the world's oil typically flows, by ordering a blockade on all vessels entering or leaving Iranian ports.
- Republican Unity is Fracturing
Sens. Susan Collins of Maine and Rand Paul of Kentucky were the only Republicans breaking with their party as Congress again declined to assert its authority over a war that has entered its eighth week without formal approval. Significantly, it was the first time Collins had voted for such a measure, making her the first Republican to do so since the war began in late February.
- The Administration Faces Multiple Legal Pathways
Other lawmakers point to a 30-day extension provision in the 1973 law as they insist that the president can continue to conduct the war without congressional approval. Under the law, Trump can extend the 60-day clock for another 30 days if he argues that continued military action is needed to keep service members safe while withdrawing from the war.
The Legal Dispute
Katherine Yon Ebright, an attorney at the Brennan Center's Liberty and National Security Program, said it's possible that the Office of Legal Counsel tries to argue that the ceasefire stopped the 60-day clock and any further hostilities reset the clock altogether. But she said "that is not something that by its text or by its design the War Powers Resolution accommodates." "But there is a long history of executive branch lawyers willfully misinterpreting the War Powers Resolution to allow presidents to conduct hostilities even past that 60-day clock," Ebright said.
The Trump administration's position rests on a factual claim, that hostilities have ceased, rather than a statutory interpretation. A Trump administration official told Reuters: "For War Powers Resolution purposes, the hostilities that began on Saturday, February 28, have terminated." The official said "There has been no exchange of fire between US Armed Forces and Iran since Tuesday, April 7."
However, this characterization is contested. Adam Schiff, a Democratic senator from California, challenged the argument, pointing out that US forces remain active in the region despite the halt in air attacks. "Ceasing to use some forces while using others does not somehow stop the clock," he noted.
Congressional Dynamics
Since the start of the war, Republicans in the House and Senate have blocked more than half a dozen Democratic war powers resolutions that would explicitly limit Mr. Trump's ability to further strike Iran. Some GOP members have indicated that their stance could change after the statutory 60-day deadline.
The Collins defection signals potential Republican fracturing. While Republicans have so far shown little willingness to curtail the ongoing U.S. military action, a growing number have said Congress needs a say. "As I have said since these hostilities with Iran began, the President's authority as Commander-in-Chief is not without limits," Sen. Susan Collins, R-Maine, said in a statement after voting in favor of Democrats' latest War Powers vote.
Strategic Stalemate
Washington and Tehran are now locked in a high-stakes stalemate. Trump has responded to the Islamic Republic's effective seizure of the Strait of Hormuz, a chokepoint through which a fifth of the world's oil typically flows, by ordering a blockade on all vessels entering or leaving Iranian ports. After the president suggested the blockade could persist for months, the global oil price hit a wartime high on Thursday, with Brent crude briefly topping $126 a barrel.
