United States ( US) President Donald Trump told congressional leaders Friday that hostilities with Iran had "terminated" under a ceasefire, arguing additional authorization from lawmakers was not required to continue military operations.
In a letter to Congress, Trump said there had been no exchange of fire with Iran since a ceasefire took effect.
"The hostilities that began on February 28, 2026, have terminated," he wrote.
The letter came on the deadline under 1973 War Powers Resolution, which requires a president to end military action after 60 days absent congressional authorization or seek a 30-day extension for troop safety during withdrawal.
Trump formally notified Congress of conflict 48 hours after initial airstrikes two months ago, starting the 60-day clock ending 1 May, 2026.

On Friday, Iranian state news agency IRNA said Tehran had sent a new proposal for negotiations with the US via Pakistani mediators, but Trump rejected the proposal, according to reports.
A senior administration official said Thursday the administration’s view was that the War Powers deadline did not apply.
Trump had previously said he considers the law unconstitutional.
Both Republican and Democratic presidents have argued the measure limits commander-in-chief powers. Legal experts note courts have not settled the matter.
"We had a ceasefire, so that gives you additional time," Trump told reporters before departing Washington for Florida.
