As of 15/05/2026, the United States Congress has effectively deferred its constitutional oversight regarding the conflict in Iran to the executive branch. Despite a clear 60-day deadline mandated by the War Powers Resolution for congressional authorization of hostilities, the Republican-led Senate has repeatedly rejected measures to halt or constrain President Donald Trump’s military engagement.
The administration’s position relies on the claim that a "ceasefire" has effectively terminated hostilities, rendering the 60-day authorization window inapplicable, despite reports of ongoing attacks and a naval blockade of Iranian ports.
Legislative Stagnation
The Senate has held multiple votes on war powers resolutions since the conflict began on February 28, 2026. While a small faction of Republican senators—including Lisa Murkowski, Rand Paul, and Susan Collins—has recently broken ranks to support checks on presidential power, the party remains largely aligned with the administration.

Executive Maneuvering: Defense Secretary Pete Hegseth argues that the operational "pause" in active strikes stops the clock on war powers limitations.
Institutional Avoidance: Senate Majority Leader John Thune has signaled no intent to bring a formal authorization-for-use-of-military-force (AUMF) vote to the floor, maintaining a status quo of legislative silence.
Democratic Opposition: Minority Leader Chuck Schumer and others have labeled the administration’s "terminated" status for the war as a misrepresentation of the reality on the ground.

Contextual Background
The conflict initiated following coordinated U.S.-Israeli strikes on Iranian military infrastructure in late February, prompted by tensions in Iraq, Syria, and the Strait of Hormuz. While President Trump recently rejected new diplomatic overtures from Tehran, signaling a review of fresh military options, internal GOP unity is facing pressure ahead of midterm elections.
Polling suggests that while the base maintains support for the President, the broader electorate is increasingly critical of the conflict's legitimacy. By choosing to avoid a formal vote, Congress has circumvented the legal requirement to authorize the war, leaving the duration and scope of the engagement entirely at the discretion of the White House.
