President Trump notified Congress on July 13, 2026, that hostilities against Iran resumed on July 7, formally starting a new 60-day window for military operations under the War Powers Resolution. Reuters

The War Powers Resolution, passed in 1973, requires the president to tell Congress within 48 hours when U.S. forces are sent into armed conflict. It also limits military action to 60 days unless Congress authorizes an extension. The administration's letter, first reported by Reuters, treats the resumption of hostilities as a fresh authorization period. Politico and The Hill independently confirmed the notification. Politico reported that the administration views the letter as resetting the 60-day clock for military action. Politico The Hill reported that Trump formally informed Congress of the Iran war resumption, noting that under the War Powers Resolution, the president can extend the U.S. military's stay beyond the initial 60-day period.

NPR, reporting on July 16, framed the notification as an effort to "reset war powers clock amid growing political risks." The report, by Franco Ordoñez and A Martínez on Morning Edition, said the administration issued the notification specifically to restart that 60-day countdown for military action against Iran. NPR

The notification arrives after months of legislative pushback. The House approved a war powers resolution to halt U.S. military action against Iran on June 3, 2026, according to the Associated Press. AP The Senate followed with its own approval on June 23. AP

The congressional resistance runs alongside the administration's shifting posture toward Tehran. In early May, Trump said he was "not satisfied" with Iran's latest proposal to end the war, citing "disjointed" leadership in Tehran. At that time, the Associated Press reported that Trump said hostilities with Iran had "terminated." AP The July notification reverses that characterization.

The administration has positioned its Iran policy on multiple executive fronts since February. On February 6, 2026, Trump signed Executive Order 14382, "Addressing Threats to the United States by the Government of Iran," reaffirming the ongoing national emergency with respect to Iran and establishing a process to impose tariffs. The White House published a corresponding fact sheet the same day. The White House Office of Management and Budget also released a Statement of Administration Policy concerning Iran regarding actions "That Have Not Been Authorized by Congress," dated April 30, 2026.

As of July 14, the White House presidential actions landing page listed no notification, statement, or entry related to Iran or the War Powers Resolution among its first-page items spanning June 29 through July 14.

Secretary of Defense Pete Hegseth has publicly said that the administration complied with War Powers Act notification requirements. In a June 2025 transcript published on defense.gov, Hegseth said Congress was notified about a military action after planes were safely out of the operation. DoD

The broader context here is the structural tension between the executive branch's use of the War Powers Resolution as an operational framework and Congress's repeated attempts to reassert its constitutional authority over hostilities with Iran. Think of the 60-day clock like a stopwatch: each time the administration declares a new resumption of hostilities, it argues that the stopwatch resets from zero. Congress passed war powers resolutions in both chambers to stop that reading, arguing the conflict is one continuous engagement under a single authorization period. The administration has not said whether it considers those resolutions binding, and the April 30 Statement of Administration Policy referencing actions "not authorized by Congress" suggests the White House is preparing to contest any legislative constraint on the president's authority to direct military operations against Iran.

The 60-day clock triggered by the July 13 notification would run into mid-September 2026.
