Constitutional Showdown: Congress Moves to Curb Trump’s War Powers After Iran Strikes

Tensions in Washington have surged following the launch of Operation Epic Fury on February 28, 2026 — a sweeping joint military campaign carried out by the United States and Israel against Iran. The operation, which reportedly resulted in the death of Supreme Leader Ali Khamenei, has ignited a sharp constitutional dispute over the limits of presidential war powers. In response, lawmakers are moving swiftly to advance a resolution aimed at preventing President Trump from continuing military action without direct approval from Congress.
In the Senate, Tim Kaine is spearheading the effort, pressing for an immediate vote on a War Powers Resolution. He has described the strikes as a grave miscalculation, arguing that the Constitution assigns the authority to declare war to Congress, not the executive branch. Kaine is urging senators to formally state their positions on what he views as a unilateral decision to initiate a major military action without legislative consent.
A similar push is underway in the House, led by an unusual bipartisan partnership between Ro Khanna and Thomas Massie. They argue that the administration failed to demonstrate the kind of imminent threat necessary to justify acting alone and are calling for greater accountability regarding the potential consequences for American personnel. Massie, long critical of overseas interventions, has warned that engaging in discretionary conflicts undermines constitutional safeguards.
The White House has rejected these criticisms, portraying the operation as a strategic success that neutralized a longstanding nuclear danger and opened the door to a potential shift in regional dynamics. President Trump has invoked his Article II authority as Commander-in-Chief, asserting that the strikes were essential to prevent a larger crisis. Administration officials maintain the action was defensive in nature, intended to stop a significant Iranian attack before it materialized.
The urgency surrounding the debate has intensified following confirmation of U.S. casualties from Iranian retaliatory strikes. According to the Pentagon, missile and drone attacks on American installations in Kuwait and the UAE resulted in the deaths of at least three service members. These developments have strengthened the concerns of lawmakers who worry the United States could be sliding into a prolonged conflict without a defined strategy or public mandate.
Even with growing support for the resolution, imposing a meaningful constraint on executive authority will be challenging. Should both chambers approve the measure, President Trump is widely expected to veto it. Overriding that veto would require a two-thirds majority in both the House and Senate — a difficult hurdle in a politically divided environment where many Republicans continue to back the administration’s assertive national security approach.
As the constitutional struggle unfolds in Washington, the regional situation continues to deteriorate, with groups such as Hezbollah and various Iraqi militias becoming increasingly involved. The coming days may prove pivotal in determining whether Congress can reestablish its influence over decisions of war and peace — a development that could shape the future of American foreign policy and presidential power for years to come.
