President Donald Trump on Friday told Congress the Iran war has ended.

In letters to top Republicans in the House and Senate, Trump said a weekslong ceasefire remains in place and that there’s been no more fighting.

“There has been no exchange of fire between United States Forces and Iran since April 7, 2026. The hostilities that began on February 28, 2026, have terminated,” Trump said in letters to House Speaker Mike Johnson (R-La.) and Senate President Pro Tempore Chuck Grassley (R-Iowa).

At the same time, Trump said the U.S. military “continues to update its force posture” in the region in response to Iranian threats. He told reporters Friday the U.S. Navy is maintaining a blockade of the Strait of Hormuz.

The letter is less about the war actually changing than the Trump administration trying to comply with the War Powers Resolution, a 1973 law that requires hostilities to cease within 60 days if Congress hasn’t authorized the use of force. Several Republicans in the House and Senate have warned about the 60-day deadline while voting against Democrats’ repeated attempts to end the war. Sen. Susan Collins (R-Maine) on Thursday became the second Senate Republican to vote for an antiwar resolution as the deadline approached.
