Key takeaway

Murkowski missed her own 28 April AUMF target; the bill remains unfiled 24 hours before the WPR deadline.

Senator Lisa Murkowski's draft Iran AUMF (Authorisation for the Use of Military Force) remains unfiled on Congress.gov as of Wednesday 29 April 2026, missing her own 28 April target by a day with the War Powers Resolution (WPR) 60-day deadline 24 hours away. The signing pen at The White House has produced no Iran executive paper across the same 60 days, matching the unfiled bill on the legislative side.

The AUMF is a joint resolution that would give legal footing to ongoing US hostilities against Iran by formally authorising the executive's use of force; without one, the Senate's 22 April rejection of the fifth WPR resolution 51-46 becomes the only congressional vote on the war. Susan Collins of Maine, Thom Tillis of North Carolina and John Curtis of Utah are named co-sponsors; Curtis was confirmed as the third Republican backer five days before the deadline. The bill needs a Senate Joint Resolution number on the public record to advance; until it has one, the 'AUMF' is a draft circulating inside Murkowski's office, not a vehicle Congress can pick up.

A filed S.J.Res. would flip the war from no-text to adversarial-text. The WPR's 60-day clock requires either a presidential withdrawal of forces or a congressional authorisation; a filed AUMF gives the Senate a procedural vehicle to vote. Murkowski had targeted 28 April for introduction per Jewish Insider reporting, three calendar days ahead of the Friday deadline to allow floor positioning. Missing the target by a day compresses that runway to roughly a single day, inside which Senate leadership must agree on a unanimous-consent track or the bill goes through full Rule XIV first reading. The Senate Foreign Relations Committee has not held a markup or hearing on a Hormuz AUMF in 60 days, an unusual gap that places the bill outside the committee process the WPR architecture assumes.

The procedural choreography that would convert the draft into a numbered resolution is missing on both ends. President Trump has signed nothing on Iran since 28 February, and Senator Murkowski has filed nothing on Iran across 60 days of war. The WPR clock will expire this Friday against an unbroken streak of paper that does not exist.

Deep Analysis

In plain English

When the US goes to war, Congress is supposed to formally authorise it through a bill called an Authorisation for the Use of Military Force. Republican Senator Lisa Murkowski of Alaska has been trying to write one, with support from Senators Susan Collins, Thom Tillis and John Curtis. Murkowski set herself a target of introducing the bill on 28 April. She missed it. As of 29 April, no bill number had appeared on Congress.gov. The legal clock for the war expires at 12:01 EDT on 1 May. When that happens, Murkowski's four-person coalition will have let the window close without producing any text to force a Senate vote.

Deep Analysis

Root Causes

The structural problem Murkowski faces is that an Iran AUMF filed under WPR pressure has two audiences with incompatible demands. Senate Republicans who support the war want an authorisation with minimal constraints.

Senate Democrats who oppose the war want a bill with geographic limits, duration caps, and oversight requirements that would effectively restrict operations. A bill that satisfies neither bloc cannot pass; a bill that satisfies Republicans passes but is indistinguishable from a blank cheque; a bill that satisfies Democrats triggers a White House veto threat.

Murkowski's draft reportedly includes reporting requirements and a 90-day duration cap subject to renewal. Those constraints are enough to make the bill unacceptable to The White House, which has privately communicated that any AUMF with operational constraints would be vetoed, removing the political incentive for Republican senators to vote for a text that will not become law.

What could happen next?

Risk
If the AUMF remains unfiled when the WPR clock expires at 12:01 EDT on 1 May, the White House will have established that a 60-day military operation can conclude its mandatory authorisation window with zero signed instruments and no legal consequence, setting a precedent for all future administrations.
Opportunity
Murkowski could file the AUMF on 29-30 April, after the 28 April miss but before the 1 May deadline, converting the missed target into a same-week introduction that still engages the WPR clock before expiry.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: The 2003 Iraq War AUMF negotiations provide the most instructive precedent for how intra-Republican legislative dynamics shape executive war authority. In September 2002, Republican senators including John McCain and John Warner extracted sunset clauses, reporting requirements, and geographic limitations from the Bush administration before agreeing to support the AUMF text.

Those constraints were modest and largely unenforceable in practice, but they established that Republican senators could extract concessions even on war authorisations their party broadly supported. Murkowski's four-person caucus is smaller than McCain's 2002 coalition but operates against an executive branch that has already demonstrated willingness to run 60 days without any written authority.

Counter-parallel: The 2002 AUMF was filed seven weeks before the November midterm elections, giving Republican senators who backed constraints political cover for doing so. The 2026 AUMF is being drafted with the midterm elections 18 months away, reducing the immediate political reward for Murkowski's caucus to press for constraints and increasing the cost of appearing to limit a president within their own party on a war that polling shows Republican voters support.

Consensus view: The Congressional Research Service's legislative analysis of WPR precedents documents that an unfiled AUMF one day before deadline converts the WPR's clock from a political pressure instrument into an abstract legal violation: the executive branch has received no formal congressional authorisation, but the mechanism to force one has also failed to materialise.

CRS notes this is the pattern in every prior WPR clock expiry since Kosovo in 1999, where the political will to file an AUMF and force a vote has consistently proven insufficient in the face of White House opposition.

Counter-view: CSIS's International Security Programme argues Murkowski's delay is a deliberate holding action to preserve the threat of an AUMF without triggering the constraints one would impose: an unfiled AUMF generates more executive-branch compliance pressure than a filed one that gets voted down, because The White House cannot neutralise it by defeating it on the floor. Under this reading, Murkowski's 28 April miss was tactical rather than a failure.

Key tension: Whether filing an AUMF with four Republican co-sponsors before the WPR deadline would have forced a Senate vote with a realistic chance of passing with constraints attached, or whether the executive branch had sufficient Republican votes to defeat any constraining text, making the AUMF a symbolic exercise in either case.

This Event

Murkowski AUMF still missing on Day 60

A filed bill would flip the war from no-text to adversarial-text and force Congress to vote up or down inside the WPR clock. Four named Republican supporters, Murkowski, Susan Collins, Thom Tillis and John Curtis, are still waiting on an introduced S.J.Res. while the deadline at 12:01 EDT on Friday 1 May runs against zero signed presidential paper.

Different Perspectives

United States (Joint Maritime Information Center)

The JMIC, the US-led naval reporting cell, rated the Hormuz threat "severe" in its 25 October advisory, as reported by gCaptain, and warned of possible renewed mining. Eight days earlier it found no substantiation for the Guards' mine claims, while US-facilitated transits ran at about 34 a day.

United Kingdom (CPS and Counter Terrorism Policing)

The CPS charged two men under the National Security Act 2023 over the RAF Fairford incident, and Counter Terrorism Policing said it believes the foreign intelligence service involved is Iran's, LBC reported. The case now runs through the courts; both men are charged, not convicted.

Aden and Yemen's recognised government

The Houthis told people to leave Aden airport, in the government-held south, before a missile fell there on 28 October, AFP reported, and police reported a second attack that afternoon. The fight between Riyadh and the Houthis is landing on the south's main civilian airport.

Qatar (mediators)

Qatar-led mediators put new terms to Iran this week, which an Iranian official called "ideas, not a proposal". Riyadh framed the Tehran meeting as support for Qatari and Pakistani mediation, keeping Doha at the centre of the indirect channel.

Korea Shipowners' Association

The association said the ships Iran listed were sub-chartered to an overseas oil company, not owned by Sinokor, carried no South Korean crew, and that Sinokor was unaware of the warning. South Korea's shipowners are contesting whose vessels the notice covers before it takes effect.

Kuwait (foreign ministry)

Kuwait summoned Iran's ambassador, Mohammad Toutounji, and handed him a protest note over the embassy's denial that its citizen took part in the alleged plot against Interior Minister Fahad Al-Yousef. Kuwait is answering through its courts and a diplomatic protest, citing international law and the UN Charter.
