The War Powers Resolution (WPR) 30-day wind-down clock, running from the 1 May Senate vote of 50-47, lapsed for a third time on Monday 1 June while the House of Representatives stayed on Memorial Day recess. The WPR is the 1973 law that lets Congress order a president to stop hostilities it never authorised; its wind-down is self-executing on paper, yet forcing the vote that gives it teeth requires a privileged resolution, and leadership controls the calendar.
Speaker Mike Johnson had pulled the floor vote once already on Thursday 21 May rather than record a loss , and the recess was scheduled straight across the cliff . What he cannot pull again is the legislative clock that Gregory Meeks, ranking Democrat on the House Foreign Affairs Committee, started by offering SJ Res 59 on the floor before the break. That clock strips the Speaker of calendar control and compels a floor vote when the chamber returns on Tuesday 2 June 1.
When the House returns on 2 June it votes at the end of Meeks's clock, with no procedural off-ramp left to leadership. Pass the resolution, and the 119th Congress imposes the first legal constraint on a war now in its fourth month. Fail it again, and a president's war authority is ratified by the body built to check it. The mechanism behind the headline is the asymmetry the WPR has carried since 1973: a floor loss costs a Speaker more politically than a quiet lapse costs anyone legally, which is why no sitting president has ever been forced to halt a war the resolution was invoked against.
