A Senate Foreign Relations Committee discharge motion cleared 50-47 on 19 May 2026, placing the Kaine war-powers resolution on the floor calendar. The discharge procedure bypasses committee-level blockage without a floor vote: it required a simple majority to remove a bottled bill, not the 51-vote threshold for passage. Bill Cassidy of Louisiana was among the four crossing Republicans — his first such crossing on any Iran legislative instrument and the vote that provided the decisive margin the 13 May attempt lacked. The procedural advance sends the resolution to the floor before 1 June 2026 , the deadline under the 1973 statute's wind-down provision. This is the eighth such attempt and the conflict's first successful procedural advance after seven committee or floor defeats.
Eighth war-powers attempt cleared after seven defeats, sending a binding floor vote before the 1 June WPR wind-down expiry; Cassidy's first Iran cross supplied the margin missing on 13 May.
