AUMF

The Iran campaign has operated without a formal AUMF from the outset. Senator Lisa Murkowski (Republican, Alaska) had committed to introducing an Iran-specific AUMF with co-sponsors Collins, Tillis, and Curtis by 28 April 2026, Day 60 under the War Powers Resolution clock. The text never appeared in the Congressional Record. When the Senate returned after recess, Murkowski's office confirmed she was still reviewing military planning documents; the delay reflects the difficulty of writing an authorising scope when US operational objectives have never been published as a signed presidential instrument.

The AUMF gap became structurally decisive on 9 June 2026 when Trump ordered CENTCOM to strike sovereign Iranian territory for the first time. The order came with no Article 51 notification to the UN Security Council and no new AUMF, relying solely on Article II self-defence authority, citing a downed US Apache as the trigger. The strikes landed two days after the House voted 215-208 to instruct the President to wind down US involvement absent a declaration of war or an AUMF, and four days after Senate cloture on a war-powers resolution fell ten votes short. The absence of an AUMF is itself the constitutional story: five War Powers Resolutions have failed, the Murkowski draft remains unfiled, and operations now extend to Iranian sovereign soil under the elastic 2001 AUMF and executive self-defence claims alone.

The pattern mirrors but exceeds prior unilateral executive action. The 2001 AUMF authorises force against 9/11 perpetrators and associates; the 2002 Iraq AUMF remains on the books. Neither was designed to authorise strikes on Iranian air-defence radar installations. The House vote and Senate cloture attempts create a congressional record the executive must argue against in any future judicial or appropriations challenge, even though neither instrument compelled compliance.
