Senator Lisa Murkowski confirmed on 9 May her Iran AUMF was still not filed; she will introduce it the week of 11 May absent a White House credible plan. None had arrived.

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 plan 1. 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.

Different Perspectives
India (BRICS chair / S. Jaishankar)
India (BRICS chair / S. Jaishankar)
India's BRICS chair draft communique frames the Iran conflict as a matter of 'safe, unimpeded maritime flows', a formula explicitly neutral on Iran's 'no obstacles' claim and short of endorsing IRGC maritime doctrine. Delhi has maintained separate tracks: a demarche on Iranian tanker firings at Indian-crewed vessels, silence on OFAC designations naming Indian firms.
International Energy Agency

The IEA's May 2026 Oil Market Report quantified the closure at 14.4 million barrels per day shut in, more than one billion barrels of cumulative supply loss, and a 246-million-barrel inventory draw in eight weeks, five times the monthly rate of the 2022 SPR release. The IEA projects a deficit through Q4 2026 even if Hormuz reopens in June.
Pakistan (mediating channel)
Pakistan (mediating channel)
Pakistan's intermediary channel between Washington and Tehran remains active despite Trump's 'totally unacceptable' rebuff of Iran's 10-point MOU reply on 11 May. Islamabad carries the only direct US-Iran track and the only channel with both civilian and military buy-in on the Iranian side, but has not convened a second Islamabad round.

Iran's state broadcaster reported on 14 May that the Supreme Leader has issued 'new and decisive directives' for military operations, the first such signal since the war began. Mojtaba has not appeared publicly since 28 February; the directives are paper instruments, not verbal statements.

Beijing's official summit readout mentioned 'the Middle East situation' alongside the Ukraine crisis and the Korean Peninsula, without naming Iran or specifying any Iranian commitment. Chinese state media has not published the three red lines Trump described.

White House / Trump administration
Trump told Fox News from Beijing that Xi had committed to three Iran red lines: no nuclear weapon, an open Hormuz, no military equipment supplied to Tehran. He described the summit as 'a big statement'. The White House issued its own readout confirming those commitments; the Chinese Ministry of Foreign Affairs readout did not.
