The White House asserted to Congress in a letter Friday that hostilities with Iran have "terminated" despite the continued presence of U.S. armed forces in the region. The message from President Donald Trump effectively skirts a May 1 legal deadline to gain approval from members of Congress to continue the war with Iran. That deadline was already set to pass without action from Republican lawmakers who are deferring to the president. The letter brings into stark relief the bold but legally questionable assertion of presidential power at the heart of Trump's war, which he began without congressional approval two months ago.

"The hostilities that began on February 28, 2026, have terminated," Trump wrote House Speaker Mike Johnson, R-La., and Sen. Chuck Grassley, R-Iowa, the Senate president pro tempore. He also made it clear in the letter that the war may be far from over. "Despite the success of United States operations against the Iranian regime and continued efforts to secure a lasting peace, the threat posed by Iran to the United States and our Armed Forces remains significant," the Republican president said. Under the War Powers Resolution of 1973, Congress must declare war or authorize the use of force within 60 days - Friday was the deadline - or within 90 days if the president asks for an extension.
