Hegseth: Article 2 covers Iran war

3 min read

Defence Secretary Pete Hegseth told Senate Appropriations on 12 May that Donald Trump has 'all the authorities he needs under Article 2' and an Iran AUMF is unnecessary. The single line, delivered under oath on $29 billion of war spending, converts 75 days of unsigned Iran paper from oversight into stated doctrine.

Key takeaway

Hegseth told Senate Appropriations on 12 May that Article 2 covers Iran strikes, making any AUMF unnecessary.

Pete Hegseth, the US Secretary of Defense, testified to the Senate Appropriations Committee on 12 May 2026 that Donald Trump has "all the authorities he needs under Article 2" and that an Authorisation for the Use of Military Force (AUMF) on Iran is not required ¹. The reply came under oath, on $29 billion of war spending, in answer to a question from Lisa Murkowski about whether an AUMF would help the President. "We don't need it," Hegseth said. The Washington Post described the appearance as marked by "intense bipartisan frustration".

The Senate Appropriations Committee is the panel that writes the Pentagon's cheques, not the panel that authorises war. That jurisdictional setting matters. Rand Paul and Susan Collins, who crossed the floor on the 30 April War Powers Resolution vote alongside Murkowski's four co-sponsors, were not in the room. The doctrinal moment landed in front of the committee that funds the operation rather than the committee that would constrain it. Article 2 of the US Constitution is the Commander-in-Chief clause; the executive branch has historically reserved Article 2 self-defence claims for short-window operations, not for 75-day sustained campaigns with declared blockades and 15,000 deployed personnel.

The testimony supersedes Murkowski's threatened Iran AUMF, still unfiled after the 9 May deadline passed , and rereads Trump's three contradictory 8 May Truth Social posts as the rhetorical surface of a settled administration position rather than a communications muddle. In practical terms the 60-day War Powers Resolution clock and the 30-day wind-down clock both lose their bite: if no AUMF is required, no clock can run out on a missing authorisation. The last US coercive Iran action before Hegseth spoke was OFAC's 11 May Hong Kong sweep , a Treasury-initiated package rather than a signed presidential instrument ².

Hegseth's appearance is the first time a cabinet officer has named the verbal-track method as policy rather than denied it. Every prior Trump pronouncement on the war ran through Truth Social or the briefing room. This one was sworn testimony in front of the appropriators. The constitutional weight depends on whether the Office of Legal Counsel, if asked, matches the position; the political weight does not.

Deep Analysis

In plain English

In the United States, only Congress can formally declare war. But a 1973 law called the War Powers Resolution was supposed to give Congress a way to stop the president from fighting wars indefinitely without approval. It says the president must get congressional sign-off within 60 days. Pete Hegseth is the man in charge of the US military. On 12 May, he sat before a Senate committee and said, under oath, that President Trump does not need Congress's approval to keep fighting in Iran. He said the president already has all the authority he needs under Article 2 of the Constitution, which is the part that makes the president commander in chief. That matters because the US has been fighting Iran for 75 days with no formal paperwork: no signed executive order, no congressional authorisation, nothing. Hegseth's testimony converts what looked like a paperwork delay into a deliberate legal strategy; the administration is saying it simply does not need the paperwork.

Deep Analysis

Root Causes

The structural condition enabling Hegseth's testimony is a legal gap the War Powers Resolution never closed: the statute defines "hostilities" as triggering the 60-day clock, but provides no mechanism to compel a president to acknowledge that hostilities exist.

The five WPR votes on Iran each required the losing side to accept the executive's characterisation as final. No court has ever ruled that the President must accept a concurrent congressional resolution as binding; Morrison v. Olson (1988) and Zivotofsky v. Kerry (2015) both reserved the war-powers question explicitly.

The second structural cause is jurisdictional: Hegseth testified before Senate Appropriations, which controls Pentagon funding but cannot deauthorise a war. Senator Collins chairs that committee. Under the administration's own logic, the appropriators can defund but cannot deauthorise, giving Congress a brake but not a veto. By placing the doctrinal statement in front of the spending panel, the administration acknowledged financial leverage while denying constitutional constraint.

What could happen next?

Precedent
A sworn cabinet testimony naming the verbal-track method as Article 2 doctrine sets a precedent that future administrations can cite for sustained military campaigns without signed instruments.
Long term · 0.8
Consequence
The War Powers Resolution 60-day and 30-day clocks lose effective force if no court will compel the executive to acknowledge "hostilities", rendering the statute unenforceable absent a congressional funding cut.
Short term · 0.85
Risk
The Office of Legal Counsel, if asked to produce a formal opinion, may not match Hegseth's position, creating an internal executive branch contradiction that opposing counsel could exploit.

Primary parallel: In 1983, President Reagan deployed Marines to Beirut under a 60-day War Powers Resolution clock, then retroactively obtained an 18-month Multinational Force in Lebanon Resolution from Congress before the clock expired.

The Administration's theory was that the deployment was a peacekeeping operation, not "hostilities," and therefore no clock had started. The Beirut precedent is structurally similar: a sustained deployment, a contested legal framing, and a Congress unwilling to force a floor vote that might lose.

Counter-parallel: President Clinton's air campaign over Kosovo in 1999 ran 78 days without a declared war or AUMF. Congress passed a bill to fund it but rejected the declaration of war. The key difference: Kosovo had zero signed White House instruments and no congressional testimony naming the legal theory. Hegseth's 12 May appearance is the first time a senior cabinet officer has formally named the verbal track as settled policy rather than contested interpretation.

Consensus view: The Brennan Center for Justice and Harvard Law's National Security Law program both assess that Article 2 self-defence claims have never previously been applied to a sustained naval blockade of this duration with a five-digit forward-deployed force.

The constitutional floor for Article 2 unilateral action, set in Justice Jackson's Youngstown Steel concurrence, requires either a genuine emergency or the absence of congressional disapproval; neither condition fits a months-long campaign that has already survived five War Powers Resolution votes.

Counter-view: The Foundation for Defense of Democracies in Washington and the Begin-Sadat Centre in Tel Aviv argue that Hegseth's testimony is strategically sound: by naming the verbal-track method as settled doctrine before any congressional challenge matures, The Administration forecloses the legal ambiguity that gave the WPR votes their momentum (ID:3213).

Key tension: Whether an Article 2 claim made under oath before Senate Appropriations, the spending committee rather than the authorising committee, carries sufficient institutional weight to bind a future court, or whether it is simply a political declaration that the Office of Legal Counsel has yet to ratify.

Different Perspectives

Human rights monitors (Hengaw, Amnesty International, Iran HRM)

Monitors documented a second death sentence for Zahra Tabari, 68, reported cemetery record deletions at Behesht-e Zahra, and a poll showing 81.5% of medical residents want to emigrate, against a background of 200+ confirmed executions since February. Iran's security courts operate at uninterrupted wartime tempo regardless of the diplomatic track.

Pakistan (mediator)

Islamabad carried Trump's revised MOU demanding HEU destruction to Iranian negotiators, formally inheriting the role of sole active mediator after Oman's forced withdrawal. Pakistan lacks Oman's banking infrastructure for frozen-asset routing and carries its own regional stakes, making it a less structurally neutral broker.

Kuwait

Kuwait intercepted Iranian missiles and drones for a second time in days on 1 June, with air-raid sirens sounding nationwide, after invoking Article 51 self-defence on 28 May following the Ali Al Salem ballistic-missile strike. The repeated interceptions test whether Kuwait's domestic politics can sustain hosting US forces as a de facto co-belligerent.

China (PRC)

Beijing sent scholars to Shangri-La rather than its defence minister and addressed Taiwan without mentioning Iran, maintaining bilateral energy corridor protection with Tehran while refusing diplomatic exposure at multilateral forums. Trump barred China as an HEU custodian on 27 May, removing Beijing from the deal architecture while China continues supplying DPI hardware that caps Iran's internet.

Lloyd's of London / war-risk underwriters

Lloyd's held its Hormuz war-risk designation at $10-14 million per voyage while Brent recovered to $93.91, maintaining the structural divergence from futures pricing that has persisted since late May. Underwriters require a UN Security Council resolution or government certification letter, not diplomatic optimism.

Gulf Cooperation Council states (Saudi Arabia, UAE, Bahrain, Qatar)

Five Gulf states wrote to the IMO on 21 May rejecting Iran's PGSA transit authority over international waters; Saudi Arabia and the UAE have not confirmed participation in the European Hormuz mission. The GCC is navigating between US security guarantees and exposure to Iranian fire, with no Gulf state formally co-belligerent except Kuwait.
