Senator Lisa Murkowski's draft Iran AUMF, targeted by her own office for 28 April introduction, did not reach Congress.gov by close of business. Collins, Tillis and Curtis have publicly backed the concept; nobody has filed the bill.

Key takeaway

Murkowski's draft Iran AUMF missed her own filing target; the Senate now produces no instruments on the war.

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.

Deep Analysis

In plain English

The US Congress has a law , the War Powers Resolution , that says the president needs congressional approval to keep fighting a war for more than 60 days. That deadline is this Friday. The senator working on a bill to give that approval missed her own deadline to file it. Four separate Senate votes have failed to stop or authorise the war. On Friday the legal clock runs out, with no bill filed on either side.

Deep Analysis

Root Causes

Murkowski's non-filing follows a documented pattern in the Senate's handling of this conflict: four floor votes that produced a public record without a legislative instrument.

An AUMF introduced by Murkowski would be referred to the Foreign Relations Committee, where Senator Jim Risch chairs; Risch has not backed the concept, so a filed bill would die in committee without a discharge petition, a tactic Murkowski has not signalled. That procedural wall makes the Collins-Tillis-Curtis backing irrelevant: co-sponsors cannot force a bill past a committee chair who has not moved it.

The Collins-Tillis-Curtis backing is real but insufficient: three senators co-sponsoring a bill that cannot clear committee serve the same function as the four prior WPR votes , a public record of opposition without a forcing instrument.

What could happen next?

Consequence
Friday 1 May becomes the fifth consecutive legal deadline the executive and legislative branches pass without a signed Iran instrument, extending the precedent that the WPR clock has no enforcement mechanism in practice.
Immediate · 0.88
Risk
The May appropriations cycle offers the next structural lever: a continuing resolution or supplemental spending bill could attach an Iran-specific funding restriction, converting the political position into a financial constraint.
Short term · 0.65
Precedent
If the WPR clock expires without enforcement action for the sixth consecutive administration, the practical legal threshold for sustained presidential military action without AUMF shifts permanently upward.
Long term · 0.75

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: The 2011 Libya intervention under Obama ran past the WPR 60-day clock without a congressional authorisation. The Administration argued the operation did not constitute 'hostilities' under the statute's meaning. Congress debated but did not vote to cut funding; the operation continued. Obama's Office of Legal Counsel produced a written opinion to sustain the position.

Counter-parallel: The 2002 Iraq AUMF passed the Senate 77-23 with broad bipartisan support before hostilities began. The contrast with 2026 is structural: the 2002 Senate had a staffed administration presenting a defined threat case. The 2026 administration has produced no Iran threat assessment to Congress in 60 days.

Consensus view: The Brennan Center's Elizabeth Goitein assesses the non-filing as legally consequential: the War Powers Resolution's 60-day clock creates a mandatory withdrawal obligation under 50 U.S.C. § 1544(b), but Congress has never enforced it against a sitting president. The obligation exists in statute; the enforcement mechanism does not exist in practice.

Counter-view: Heritage Foundation's John Malcolm argues the WPR's 60-day clock has been constitutionally contested since 1973 and every president since Nixon has asserted the statutory constraint is an unconstitutional limitation on the commander-in-chief. The missed filing is therefore irrelevant to the legal status of the operation from the executive branch's perspective.

Key tension: Whether the combination of a missed AUMF and an expired WPR clock creates political rather than legal pressure , specifically, whether the May appropriations cycle gives war opponents a funding lever the floor-vote route has not provided.

Different Perspectives

Spain's LNG terminal operators

Spain's 9,145 GWh terminal inventory is the largest single stock in the EU LNG network, an option value that can reroute cargoes wherever the winter strip pays best rather than a cavern gas obligation tied to a fixed date. That flexibility matters more as Germany's cavern shortfall pushes more of the winter security question onto import infrastructure.

European Commission

Brussels holds the bloc to 90% on a flexible window while Germany, holding roughly a quarter of EU storage capacity, tracks toward missing its own lower 80% figure by 21 points. A national shortfall this size in the anchor market matters more to bloc security than the flexible timetable alone can absorb.

French power exporters and CRE

French day-ahead rose in step with Germany but by less, reopening a EUR 7-17 premium that makes northward export flows commercially attractive again after the EUR 43.09 discount evaporated in days. CRE separately authorised RTE and Enedis to buy flexibility locally, betting the coming winter's binding constraint is grid congestion rather than a shortage of firm capacity.

TTF trading desk

A visible national shortfall like Germany's 21-point gap is a directional signal, not noise, for a desk holding the summer-winter spread. TTF's flat EUR 58-60 range through this week's German price swings says the market has not yet chosen to reprice refill risk into the front of the curve.

German cavern and CCGT operators

German caverns kept buying prompt gas at TTF near EUR 58-60 through the inversion; the wind collapse to 2.4 GW then flipped the spark spread to plus EUR 29 and put turbines back in the same queue. Every day turbines win that bid, injection at a third of the 877 GWh/day pace needed falls further behind.

Slovakia

Slovakia says it dropped its hold-out on the 21st sanctions package only after Ursula von der Leyen personally signed written gas-price and supply guarantees. The Council of the European Union's own 17,238-character release on the package names neither Slovakia nor any guarantee, leaving Bratislava's account unconfirmed by the institutional record.
