The House passed its war-powers measure 215-208 on 3 June and sent it to the Senate, where ending debate requires 60 votes1. The vote was the first recorded congressional position of the war, inverting the 14 May tie. Only four Republicans have crossed: Susan Collins, Lisa Murkowski, Rand Paul and Bill Cassidy, leaving the resolution roughly ten votes short of cloture. The Senate's floor time for 8 June is set for a judicial nomination, not Iran.
The War Powers Resolution (WPR), the 1973 statute that caps undeclared hostilities at 60 days and requires the President to seek authorisation, has now lapsed three times in this war, on Days 60, 72 and 93, with no enforcement. The statute creates leverage for a floor vote but cannot compel one, and it carries no mechanism to force the executive to produce a signed instrument. So at the 100-day milestone the legislature can register a position yet neither chamber can compel the paper The Administration declines to sign. Foreign Minister Abbas Araghchi has coupled any movement to the unsigned memorandum of understanding, tying Lebanon's fate to the same absent signature, which keeps every clock running against a document nobody has signed.
