Ceasefire Halts Iran War Powers Clock as Congress Defers to Trump

The Trump administration insisted Thursday that its military campaign against Iran had effectively ended with a fragile ceasefire, allowing it to sidestep a statutory deadline requiring congressional approval for continued hostilities. The move comes as the conflict settles into an uneasy stalemate that has closed the Strait of Hormuz, driven oil prices to four-year highs, and imposed significant economic pain on the global economy and American consumers at the gas pump.

Defense Secretary Pete Hegseth told the Senate Armed Services Committee that the ceasefire, in effect since April 7, “means the 60-day clock pauses or stops.” A senior administration official reinforced the position in remarks to multiple outlets, declaring that “for War Powers Resolution purposes, the hostilities that began on Saturday, February 28, have terminated.” No shots have been exchanged since early April, the officials noted, even as broader diplomatic talks toward a longer-term agreement remain stalled and Iran’s supreme leader claimed victory in a televised statement.

The argument tests the boundaries of the 1973 War Powers Resolution, passed in the shadow of Vietnam to reassert congressional authority over military engagements. The law requires the president to terminate the use of American forces within 60 days of notifying Congress unless lawmakers explicitly authorize continuation or declare war. Trump notified Congress on March 2 after joint U.S.-Israeli strikes began. Friday marks the 60th day. Democrats, led by Sen. Tim Kaine of Virginia, immediately rejected the administration’s legal reasoning. “I do not believe the statute would support that,” Kaine responded to Hegseth. “I think the 60 days runs maybe tomorrow, and it’s going to pose a really important legal question for the administration there.”

The dispute highlights a familiar pattern in American war-making: presidents of both parties have often treated the War Powers Resolution as advisory rather than binding, while Congress has repeatedly failed to enforce its own prerogatives. On Thursday, Senate Republicans blocked a Democratic war powers resolution for the sixth time, mostly along party lines. Two Republicans, Sens. Susan Collins of Maine and Rand Paul of Kentucky, broke ranks to support it. Senate Majority Leader John Thune said he saw no appetite within his conference for a vote to authorize force or otherwise constrain the president.

This deference comes despite earlier private unease among some GOP lawmakers about the conflict’s trajectory. Public frustration has grown as the war’s costs mount: 13 American service members killed, billions of dollars spent, and persistent disruption in energy markets. Iran activated air defenses over Tehran late Thursday in response to what it described as small aircraft and reconnaissance drones, a reminder that the underlying tensions have not disappeared even if direct combat has paused.

The administration’s position effectively treats the ceasefire as a legal off-ramp, arguing that the absence of active fighting resets the clock. Legal scholars have long debated whether such pauses are contemplated by the statute, which speaks in terms of calendar days rather than the presence or absence of kinetic activity. The White House did not seek congressional approval before launching strikes alongside Israel, consistent with a decades-long trend of executives asserting broad commander-in-chief authority in the initial phase of conflict.

Yet the practical result is a war that began without explicit congressional consent, continues in a legal gray zone, and now faces no immediate legislative check as Congress departs for a week-long recess. The conflict’s origins lie in escalating tensions that culminated in late February strikes, but its persistence owes much to the difficulty of translating military pressure into durable diplomatic outcomes. The closed strait has rippled through global supply chains. Oil prices spiked before easing slightly, yet the uncertainty continues to weigh on markets and household budgets.

For President Trump’s second term, the Iran file has become an early and revealing stress test. The administration entered the conflict projecting decisive strength. What has followed is a costly stalemate in which both sides believe time is on their side. Iran’s leadership portrays the episode as proof of American overreach and its own resilience. Trump has warned that a naval blockade could remain in place for months if Tehran does not yield. Neither posture suggests an imminent breakthrough.

Democrats have used the repeated votes to highlight what they describe as unchecked executive power and the human and fiscal toll of a war that lacks clear congressional buy-in. Yet their procedural efforts have changed little on the ground. Republicans, for their part, have largely chosen institutional deference over constitutional assertion, calculating that challenging a president of their own party carries higher political risk than allowing the legal interpretation to stand.

The episode underscores the persistent weakness of congressional war powers in practice. The 1973 law was written to prevent future Vietnams by forcing deliberate collective judgment. In this case, as in many before it, the judgment has been deferred. The ceasefire may have paused the shooting, but it has not resolved the underlying strategic or legal questions. As the calendar flips past the 60-day mark, the Trump administration proceeds without new legislative authorization, the Strait of Hormuz remains blocked, and the costs of an unresolved conflict continue to accumulate. How long that equilibrium can hold will shape not only the fate of this crisis but the credibility of American institutions tasked with deciding when the country goes to war.
