Key takeaway

An Article I authorisation effort sharpens as the executive's verbal-only Iran posture enters its third month.

Senator Lisa Murkowski confirmed on 9 May that her Iran authorisation for use of military force (AUMF) had not been filed. The Alaska Republican stated she would introduce it the week of 11 May absent a White House credible plan⁠¹. No plan was delivered by 9 May. The Senate returns from recess on the same week the Trump-Xi summit opens on 14 May, compressing the legislative timeline to a single working week before the next forcing event.

The last signed Iran-adjacent presidential instrument was the 1 May OFAC General Licence W; the verbal track running on top of it (the carrier escort announcement, the EPIC FURY conclusion, the MOU claim) has produced no signed counterpart. The Murkowski AUMF acquires argumentative force from that gap. The constitutional argument has shifted from "is this a war the President can wage alone?" to "is this a war the President can run on Truth Social alone?".

Murkowski has voted with the bipartisan War Powers caucus through six prior unsuccessful WPR motions in this Congress; her AUMF route is the inverse approach, granting Article I authority on conditions rather than denying it. The Murkowski conditions, requiring a White House plan with verifiable benchmarks before any vote, would force the executive to sign something rather than say something. Without Susan Collins or Rand Paul signing on as co-sponsors, the bill enters a Senate where the Republican leadership has not yet conceded that 71 days of unsigned Iran posture amount to an Article I deficit. The White House has the working week before the 14 May summit to produce a written counter-text or accept the legislative pressure.

Deep Analysis

In plain English

In the US, only Congress has the power to formally declare war. But the President can deploy troops and conduct military operations using emergency powers for up to 60 days without Congress voting. After 60 days, Congress is supposed to either authorise the action formally or the troops must come home. That is what the War Powers Resolution, passed in 1973, requires. Senator **Lisa Murkowski** of Alaska wants to introduce an **authorisation for use of military force (AUMF)**, a formal congressional permission slip for the Iran war, but with conditions attached. She says she will file it the week of 11 May unless The White House produces a credible written plan for the conflict first. This matters because it would force the President to either produce signed documents or face a congressional vote. The war has run for 71 days without a single signed presidential legal instrument (no executive order, no formal authorisation). Murkowski's move is an attempt to force written accountability onto a war that has been run entirely through social media posts.

Deep Analysis

Root Causes

The Murkowski AUMF's structural logic rests on a constitutional asymmetry that the 71-day verbal-only track has exposed.

**Article I** of the US Constitution assigns Congress the power to declare war. The War Powers Resolution operationalises this through the 60-day clock, but the clock has never been successfully enforced because the Supreme Court has avoided ruling on its constitutionality, and every administration has argued that ongoing operations authorise themselves by Congress's failure to cut off funding.

The verbal-only Iran track has produced a new factual basis for the Article I argument: the President is waging a conflict without any signed presidential instrument visible in the Federal Register (no executive order, no published CENTCOM operations order, no Treasury designation with Iran specifically in scope since GL-U lapsed). An AUMF in this context would force the executive to choose between accepting conditions it has refused to commit to, or actively rejecting congressional authorisation, which produces a clean Article I test that courts could rule on.

Murkowski's specific leverage derives from her position as a centrist Republican whose vote is needed for several other White House legislative priorities. Her threat to file the AUMF functions as a negotiating instrument against an administration that needs her vote elsewhere in the same legislative session, separate from any constitutional outcome.

What could happen next?

Consequence
Without Susan Collins or Rand Paul as co-sponsors, the Murkowski AUMF enters a Senate where Republican leadership has not conceded that 71 days of unsigned Iran posture constitute an Article I deficit; the bill may not reach a floor vote.
Short term · 0.72
Precedent
If the White House produces a written plan in response to Murkowski's threat without the AUMF being filed, it would confirm that the threat of legislation is more effective than WPR enforcement mechanisms that have failed six times in this Congress.
Immediate · 0.68
Risk
The Senate returning from recess the same week as the 14 May Trump-Xi summit creates a compressed window: if the summit produces a diplomatic framework, the AUMF loses political oxygen; if the summit fails, the AUMF filing would coincide with a new escalation phase.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: The 2002 Iraq authorisation for use of military force (AUMF), Public Law 107-243, passed the Senate 77-23 and the House 296-133, but it required the President to first certify to Congress that diplomatic efforts had failed and that military action was consistent with the anti-terrorism resolution.

The Murkowski Iran AUMF inverts this: it demands a White House credible plan before the AUMF is even filed, rather than after it passes, using the threat of legislation as the forcing mechanism. That distinction matters because it puts the burden of producing a signed document on the executive before any congressional vote, which is more direct than 2002's pre-vote certification requirement.

Counter-parallel: The 1973 War Powers Resolution (WPR), enacted over Nixon's veto, established a 60-day clock for undeclared hostilities, with the President required to notify Congress within 48 hours of deploying forces. Every President since 1973 has contested the WPR's constitutionality without openly defying it to the point of a Supreme Court test.

The 2026 Senate has voted down WPR motions six times without forcing a test. Murkowski's AUMF route sidesteps the WPR's enforceability problem: rather than using the clock mechanism that Presidents have evaded for 53 years, she would create an affirmative congressional authorisation with conditions, which is constitutionally harder to ignore than a withdrawal deadline.

Causes and effects

This Event

Murkowski's Iran AUMF still unfiled before recess

Murkowski's Iran AUMF still unfiled as Senate returns

ID:3165 confirmed Murkowski had not filed as of 8-9 May; this event records the expiry of her 30 April conditional window and the Senate's return on 11 May without an AUMF filed.

Different Perspectives

Bulgarian government

Bulgaria's Prime Minister, Rumen Radev, said the sinking of HS Dignity "benefits the Russian Federation" while saying Bulgaria lacked solid evidence to accuse anyone, and Defence Minister Dimitar Stoyanov asked NATO for air defence on 16 October. The request comes from a government that stopped state military aid to Ukraine in June.

Radoslaw Sikorski

Poland's foreign minister challenged Elon Musk on X after SpaceX capped Ukraine's Starshield terminals on 14 October. Poland pays about $50m a year for Ukraine's Starlink subscriptions, so Warsaw speaks as the paying customer as well as the ally.

Andy Burnham

Burnham fast-tracked £10m of a £45m air-defence missile delivery when Zelenskyy visited London on 14 October, and his ministers are lobbying allies to ban maritime services for Russian liquefied natural gas. The measure targets insurers and shipowners, many of them in London, rather than the gas itself.

Ministry of External Affairs (India)

India's foreign ministry said after the 16 September House vote that New Delhi would take all necessary measures to protect its trade.

European Council

EU leaders on 15-16 October rejected a US idea to hand Washington the roughly €200bn of frozen Russian assets held in Europe, and Kaja Kallas said the decision belongs to Europeans. The same summit put off a decision on financing Ukraine, saying leaders "will revert to the issue in a timely manner".

Donald Trump

Trump signed the 16 October order that sets the Graham Act's duties and waives them under section 115(a), with a certification sent to Congress. He says the United States has not stopped sharing intelligence with Ukraine, and on 11 October he said both sides had agreed to halt attacks on energy infrastructure.
