May 1 Deadline Looms Under War Powers Resolution for U.S. Military Action Against Iran

Friday marks a key date under the War Powers Resolution for U.S. military action against Iran, which began with joint U.S.-Israeli strikes on February 28, 2026. President Donald Trump faces decisions on whether to terminate operations, seek congressional extension, or pursue other steps, following notification to Congress on March 2 that started a 60-day period ending May 1.

Defense Secretary Pete Hegseth stated Thursday that an ongoing ceasefire "pauses" the countdown, during a Senate Armed Services Committee hearing. Congress begins a week-long recess, amid discussions from both parties on the administration's next moves. Democrats have introduced resolutions to require halting operations without approval, while some Republicans have expressed concerns over limited congressional involvement.

The 1973 War Powers Resolution, enacted after the Vietnam War, requires the president to consult Congress before introducing U.S. armed forces into hostilities and to terminate such action within 60 days unless Congress declares war, authorizes force, or extends the period. An additional 30 days is allowed for safe withdrawal if needed. The law applies when forces are introduced into "hostilities or into situations where imminent involvement in hostilities is clearly indicated."

The Trump administration launched preemptive strikes with Israel on February 28 targeting Iran's nuclear facilities, missile infrastructure, and leadership. Officials cited Iran's advancing nuclear program and ballistic missile development—following failed diplomatic efforts—as creating a national emergency and existential threat to the U.S. and allies. The administration did not seek prior congressional authorization but has conducted over 30 bipartisan briefings with lawmakers since before the strikes began.

Iran retaliated with attacks on Israel and U.S.-allied Gulf states, leading to casualties on multiple sides and escalation until a ceasefire took effect April 7. No fire has been exchanged between U.S. and Iranian forces since then, according to a senior administration official who spoke on condition of anonymity to discuss internal positions. The official stated that, for purposes of the War Powers Resolution, "the hostilities that began on Saturday, Feb. 28 have terminated."

Hegseth declined during the hearing to confirm whether the White House would seek congressional approval and reiterated the ceasefire's effect on the timeline. Administration officials have described the action as a limited military operation expected to last four to six weeks, aimed at denying Iran nuclear weapons capability, in contrast to longer U.S. engagements in Iraq and Afghanistan.

President Trump stated Wednesday that the U.S. would maintain a blockade of Iranian ports until Tehran meets demands, including restrictions on its nuclear program. Iran closed the Strait of Hormuz to commercial shipping on April 18 amid the conflict, contributing to disruptions. The U.S. blockade followed, amid ongoing tensions.

The May 1 deadline has divided lawmakers across party lines. The Senate rejected a resolution Thursday to halt further action without authorization; it was supported by nearly all Democrats and Republican Sen. Susan Collins (Maine). Collins posted on X that presidential authority as commander in chief "is not without limits," calling the 60-day requirement mandatory and stressing that any further action needs "a clear mission, achievable goals, and a defined strategy for bringing the conflict to a close."

House Speaker Mike Johnson (R-La.) said the U.S. is "not at war," aligning with Hegseth's view that the ceasefire pauses hostilities under the resolution. "I don’t think we have an active, kinetic military bombing, firing or anything like that. Right now, we are trying to broker a peace," he told NBC News.

Other Republicans, including Sen. Mike Rounds (R-S.D.), indicated openness to a 30-day extension. "I’d be surprised if he didn’t ask for a 30-day extension," Rounds told CNN. "During that time period, we’ll be asking questions." Sen. Thom Tillis (R-N.C.) told reporters that upon Congress's return the week of May 11, discussions with the administration should lead to an authorization for use of military force "so that the American people understand that Congress is behind what the president is trying to do."

Democrats, including Sen. Tim Kaine (D-Va.), criticized the administration's position. Kaine told Axios that Hegseth's comments indicate an attempt to "find a loophole," adding, "They know they’ve got a 60-day problem, and they’re trying to come up with a rationale to get around it." Republicans have also voiced concerns about Congress's role; some called for consultation by May 1, even while opposing restrictive resolutions.

The resolution allows a 30-day extension for withdrawal if requested. Some lawmakers from both parties anticipate such a step.

Lawmakers enter recess with no formal White House communication on plans. Peace talks between the U.S. and Iran stalled after an initial round last month produced no agreement. The Strait of Hormuz remains closed to shipping by Iran, and the U.S. maintains its port blockade. Oil prices reached a four-year high earlier this week after Trump's blockade comments, amid broader economic effects from the disruptions, including elevated global costs.

The conflict has resulted in a two-month period of exchanges, now paused, with both sides reporting confidence in their positions despite the interruptions to trade routes.
