Trump Formally Notifies Congress That United States Is at War with Iran Under War Powers

BLUFTrump's stop-start War Powers framing very likely sustains military operations against Iran past the September 8 deadline without congressional authorization, as bipartisan opposition lacks the votes to compel withdrawal.

President Trump formally notified Congress on Monday that military hostilities with Iran, which he described as having "commenced on July 7," restarted a week earlier, in a letter dated July 10 and addressed to Senate President Pro Tempore Chuck Grassley 12. The notification followed Trump's declaration that the U.S.-Iran ceasefire was "over" and came after strikes on Iranian targets in response to Iranian attacks on commercial vessels in the Strait of Hormuz, with Iran countering by launching missiles and drones at U.S.-allied Gulf states 1. Trump separately announced Monday that Washington was reimposing a blockade on Iranian ports and vessels 13. The Jerusalem Post, citing the letter, reported the administration regards the notification as opening a new 60-day window for military action without congressional approval, a position Democratic Sen. Adam Schiff and Republican Rep. Thomas Massie have publicly disputed as inconsistent with the War Powers Resolution 14.

Analysis
Trump's July 10 letter resets the War Powers clock a second time, and the administration will very likely continue strikes and the Gulf blockade past the new September 8 deadline without seeking congressional authorization. The stop-start framing, already used in April to sidestep the original May 1 deadline, lets the White House recharacterize renewed combat as a fresh 60-day episode rather than a continuation of the war that began in February. Bipartisan resistance from Schiff and Massie signals congressional friction but not the votes needed to compel withdrawal, given the Senate's rejection of a prior war-powers measure. High confidence rests on the administration's consistent legal posture and the absence of any indication it intends to alter operational tempo.
