Twenty-seven days have passed since Donald Trump put his name to any Iran-related presidential action. A 14 April audit of The White House presidential-actions page confirmed the two signed Iran instruments across 45 days of war remain those of 18 March: a Jones Act waiver for foreign-flagged tankers between US ports, and an authorisation for Venezuela's PDVSA (Petroleos de Venezuela) to resume sales to American refiners1. Both were oil-price containment measures. Neither was a war-powers instrument. Every escalation since, the blockade order, the toll-interdiction list runs against it in the Senate, the 8 April ceasefire declaration and all five Hormuz ultimatums, exists only as Truth Social posts.
That absence is not a paperwork quibble. A US Navy captain boarding a foreign-flagged vessel on Saturday morning is acting on a social-media post, not a signed directive. Any flag state filing a maritime-law complaint, any master contesting the boarding, any officer later pulled into an accountability review has no presidential instrument to point to as legal cover. Agency counsels at Treasury, State and Defense have no authoritative text to implement, which is how you get Treasury's 25-day silence on GL-U, the CENTCOM operational order narrowing the blockade away from what Trump posted, and the Senate war-powers clock running against an action the White House has never formally filed.
Under the National Security Act and settled case law, a presidential social-media post is not a lawful directive to federal agencies. CENTCOM is operating under its existing statutory authority as an armed-forces command, not under a specific Iran war authority, which means the operational order it issued is self-generated in any legally reviewable sense. Congressional challenge via the War Powers Resolution is procedurally harder when no presidential report starts the statutory clock; Senate Democrats are adapting by forcing a vote anyway. The clock is still running, but it is running against a policy whose authoritative text is a screenshot.
Allies seeking legal assurance of US commitment have the same problem. France and Japan are formally protesting vessels on Trump's toll list that CENTCOM's order omits; neither government has a signed American instrument to negotiate against. Every subsequent ratchet, from Schumer's WPR push to European procurement decisions, is being made against a policy that exists only as posts.
