President Donald Trump notified Congress on May 1 that hostilities with Iran "have terminated," asserting that a ceasefire in place since April 7 satisfied the requirements of the War Powers Resolution of 1973 and eliminated the need for congressional authorization. Under the Resolution, a president may initiate military action without prior authorization but must notify Congress within 48 hours and terminate hostilities within 60 days unless lawmakers approve an extension. That 60-day clock, triggered by Trump's notification to lawmakers on March 2, reached its deadline on Friday. Congress has not authorized the military campaign. [1][2]
In nearly identical letters addressed to House Speaker Mike Johnson and Senate President Pro Tempore Chuck Grassley, Trump wrote that "On April 7, 2026, I ordered a 2-week ceasefire. The ceasefire has since been extended. There has been no exchange of fire between United States Forces and Iran since April 7, 2026. The hostilities that began on February 28, 2026, have terminated." [3][4] The letters also acknowledged that the threat from Iran "remains significant" and that U.S. force posture in the region continues to be updated, with details provided in a classified attachment. [5][6] Both chambers were on recess when the deadline passed, foreclosing immediate floor action. [6]

> **Statutory framework:** The 1973 War Powers Resolution states that, within 60 days of notifying Congress of armed hostilities, a president "shall terminate any use of United States Armed Forces … unless the Congress has declared war or has enacted a specific authorization for such use of United States Armed Forces." The statute contains no express provision pausing the clock during a ceasefire. [7]

The administration previewed its legal theory a day before the letters were sent. Asked by Sen. Tim Kaine, D-Va., about congressional authorization at the 60-day mark, Defense Secretary Pete Hegseth deferred to White House counsel but said, "We are in a ceasefire right now, which our understanding means the 60-day clock pauses or stops in a ceasefire." [8][9] The most relevant provision of the Resolution makes no mention of a ceasefire, stating instead that "within sixty calendar days" the president must "terminate any use of United States Armed Forces" unless Congress consents to an extension. [10] Trump added a parallel constitutional argument, telling reporters he would not seek authorization because "it's never been sought before" by other presidents, adding, "They consider it totally unconstitutional, but we're always in touch with Congress." [4]
The legal argument drew bipartisan skepticism. Sen. Tim Kaine told reporters that Hegseth "advanced a very novel argument that I've never heard before" and "certainly has no legal support." [11] Sen. Thom Tillis, R-N.C., said he did not "know if there's a legal basis for" pausing the clock, and said he was consulting his attorneys. [2] Sen. Susan Collins of Maine voted with Democrats on Thursday to halt the war, saying she wants to see a defined strategy and that the 60-day deadline is "not a suggestion, it is a requirement." [3] The Senate on Thursday again rejected a war powers resolution, marking the sixth time such a measure has failed. [11]
Separately, the negotiating track showed limited movement. Iran handed its latest proposal for negotiations to mediators in Pakistan, according to Iran's state-run IRNA news agency. [12] The U.S. and Pakistan did not immediately confirm receiving the proposal, and details of the plan, submitted late Thursday, were not disclosed. [12] Pakistan has served as the primary intermediary since brokering an initial two-week ceasefire on April 8; direct U.S.-Iran talks held in Islamabad on April 11 and 12 ended without a deal, with Iran's nuclear program and the status of the Strait of Hormuz as the central unresolved issues. [13] A prior Iranian proposal, transmitted through Pakistani intermediaries in late April, had offered to reopen the strait in exchange for lifting the U.S. naval blockade while deferring nuclear negotiations. Accepting that framework would have removed Trump's primary leverage for any future talks on Iran's enriched uranium stockpiles, one of the administration's stated war objectives. [14] Trump dismissed the new submission, telling reporters he was "not satisfied" with Iran's offer, adding, "Iran wants to make a deal because they have no military left," and that Tehran is "asking for things that I can't agree to."
