Senator Lisa Murkowski of Alaska did not file her draft Iran Authorisation for Use of Military Force by close of business on Tuesday 28 April, the date her office had targeted last week for introduction . Congress.gov carried no Iran AUMF bill number under her name; the Quiver Quantitative Senate-filings tracker still listed S.4236, the American Seafood Competitiveness Act, as her most recent introduction 1. An AUMF is the congressional instrument under Article I that grants the President legal authority to wage a particular war; without one the War Powers Resolution of 1973 requires withdrawal sixty days from the start of hostilities.
Susan Collins of Maine and Thom Tillis of North Carolina endorsed Murkowski's draft on Saturday 25 April ; John Curtis of Utah added his name as the third Republican backer the same day . The Senate has just rejected the fifth attempt to invoke War Powers oversight on Iran by 51 to 46 on 22 April . The political conditions for filing existed; the bill text existed; the staff drafting was complete. The act of dropping the paper into the hopper did not happen.
A filed AUMF would force the first signed Iran instrument of the war under the most adversarial conditions available to the White House. Either the president signs the bill and accepts congressional terms on his Iran policy, or he vetoes it and triggers a veto-override fight, or he ignores it and provokes an Article I confrontation. None of those options is attractive on a war The Administration has chosen to manage without paper. By not filing, Murkowski has spared The White House the choice. The Friday legal expiry will pass the way the prior four floor votes passed: without a vote on authorisation, without paper, without consequence inside the Senate's own rules.
Four failed WPR motions read as active opposition to an authorising instrument. The new pattern reads as something different. Collins, Tillis and Curtis publicly support a bill nobody is willing to make them vote on. The legislative branch has stopped producing instruments of any kind on the Iran war.
