President Trump faces a critical Friday deadline under the War Powers Resolution to end hostilities with Iran or seek congressional authorization, setting up a potential showdown with lawmakers as the conflict drags into its third month.
The Iran war began February 28. Trump notified congressional leaders March 2, triggering the 60-day clock that expires Friday under the 1973 law designed to check presidential war powers. The law requires the president to terminate military force unless Congress declares war or authorizes continued action.
Trump can extend operations for an additional 30 days to safely withdraw forces, but constitutional experts say this doesn't grant authority for offensive campaigns. "It's not a 30-day blank check for the president to continue whatever hostilities he sees fit," said David Janovsky of the Project on Government Oversight.
The deadline arrives as the war has stretched far beyond Trump's initial prediction of four to five weeks. Fighting has been mostly paused since the U.S. and Iran agreed to a ceasefire April 8 to allow for broader settlement talks, as Insider Wire previously reported.
Several Republican senators are breaking ranks over continued military action without congressional approval. Utah Senator John Curtis declared he would "not support ongoing military action beyond a 60-day window without congressional approval." Curtis argued that 60 days provides sufficient time for emergency presidential responses before lawmakers must decide "whether a state of war should in fact be declared."
Missouri Senator Josh Hawley told reporters "the statute does need to be followed" and called for an exit strategy. Senate Majority Leader John Thune of South Dakota said the administration needs "a plan for how to wind this down." Alaska Senator Lisa Murkowski is drafting a formal authorization for military force against Iran.
House and Senate Republicans have blocked more than half a dozen Democratic war powers resolutions since the conflict began. Some GOP members indicate their stance could shift after the statutory deadline passes. The resistance marks a rare instance of Republican lawmakers challenging Trump on national security matters.
The War Powers Resolution has created constitutional tensions between presidents and Congress since its passage over President Nixon's veto. Presidents from both parties have argued it unconstitutionally restricts executive authority as commander-in-chief, while lawmakers insist it protects Congress's war declaration powers.
Watch for Trump's response Friday and whether he invokes the 30-day withdrawal period or argues the ceasefire suspends the timeline, potentially forcing a constitutional showdown over presidential war powers.
