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.

Causes and effects
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
China
China
Beijing's MOFCOM Blocking Rules constrain OFAC enforcement on the mainland; China has not corroborated Trump's verbal account of any bilateral summit, and the rial's failure to hold its Rubio bounce, combined with the IRGC's stablecoin rail closure, increases Chinese yuan-denominated oil-payment exposure through Hormuz.
Israel
Israel
IDF Chief Zamir said on 3 June there is no ceasefire for his forces even as Israel signed the Washington Lebanon framework requiring Hezbollah withdrawal south of the Litani; a UNIFIL peacekeeper was killed by mortar near Marjayoun on the same day, exposing the gap between the diplomatic framework and a ground advance that has not stopped.
Bahrain
Bahrain
The IRGC struck Bahrain on 3 June as its sirens sounded and its PAC-3 magazine neared exhaustion; excluded from Rubio's 2 May emergency resupply, Bahrain received a 50-round Federal Register notice on 1 June on an 18-month delivery timeline, meaning it is defending the US Fifth Fleet headquarters on the last rounds it has.
Qatar
Qatar
Qatar offered $6bn under OFAC Licence L-2 restrictions and sent Ghalibaf's delegation home empty-handed; the $6bn ceiling is a legal constraint, not a negotiating floor, and Rubio's no-sanctions-relief testimony means Qatar cannot revise it without White House action that has not been requested.
Kuwait
Kuwait
Kuwait expelled two Iranian diplomats within 24 hours of the airport strike, the strongest and fastest Kuwaiti diplomatic move of the conflict, while keeping the full mission in place to preserve a communication channel; it has now invoked Article 51 self-defence, filed a formal protest, and expelled diplomats, exhausting its formal toolkit short of full rupture.
United States
United States
Trump narrated a weekend deal while the channel Rubio described under oath, Khamenei's written-only couriers with a 3-to-5-day lag, cannot answer at that speed; CENTCOM called the airport strike deliberate, calculated and unjustified. The House 215-208 vote gave Congress its first on-record war-powers position against the deployment Trump has run without a signed instrument for 96 days.
