The Trump administration is arguing that the war in Iran has already ended because of the ceasefire that began in early April, an interpretation that would allow the White House to avoid the need to seek congressional approval.

The statement furthers an argument laid out by Defense Secretary Pete Hegseth during testimony in the Senate earlier Thursday, when he said the ceasefire effectively paused the war. Under that rationale, the administration has not yet met the requirement mandated by a 1973 law to seek formal approval from Congress for military action that extends beyond 60 days.

A senior administration official, who spoke on condition of anonymity to discuss the administration’s position, said for purposes of that law, “the hostilities that began on Saturday, Feb. 28 have terminated.” The official said the U.S. military and Iran have not exchanged fire since the two-week ceasefire that began April 7.

While the ceasefire has since been extended, Iran maintains its chokehold on the Strait of Hormuz, and the U.S. Navy is maintaining a blockade to prevent Iran’s oil tankers from getting out to sea.
