Republican lawmakers in the U.S. House of Representatives called off a vote on a War Powers Resolution on Thursday, May 22, 2026 [1, 2].

The resolution would compel President Donald Trump to withdraw U.S. forces from the war with Iran [1, 2, 3]. Because the measure was reportedly on the verge of passing, the sudden delay creates a significant legislative hurdle for those seeking to end military involvement in the region [1, 3].

Republican lawmakers said the move was to allow lawmakers unable to attend the vote a chance to cast their say [3]. The postponement pushes the voting procedure into June 2026 [3].

Democratic lawmakers criticized the delay and said Republicans were “cowards” for postponing the vote [3]. The tension highlights a growing divide within the House over the administration's military strategy and the limits of executive war powers.

House Republicans said that ensuring full participation of the membership is necessary for the legitimacy of the vote [3]. However, the timing of the delay has led to accusations from the opposition that the majority is attempting to shield the president from a potential legislative defeat [1, 3].

The resolution specifically targets the legal framework under which U.S. forces are deployed in the conflict [1, 2]. By utilizing the War Powers Resolution, Congress seeks to reassert its constitutional authority to declare war, and oversee prolonged military engagements [2].

The resolution would compel President Donald Trump to withdraw U.S. forces from the war with Iran.

This delay represents a strategic pause by House Republicans to prevent a potential legislative defeat that would constrain the president's military autonomy. By pushing the vote into June, the GOP leadership can reorganize their caucus and potentially negotiate the terms of the resolution to avoid a direct confrontation with the executive branch over the Iran conflict.
