Senate Republicans, joined by one Democratic senator, defeated a measure late Friday that would have required President Donald Trump to obtain congressional approval before taking military action against Iran. The final vote was 53-47, with all Republicans and one Democrat opposing the resolution, according to an official statement posted on the Senate's verified social media account.

The resolution, introduced by Democratic Senator Tim Kaine, received support from 47 senators — all Democrats except for Republican Senator Rand Paul. The measure sought to compel the president to withdraw U.S. armed forces from hostilities against Iran unless Congress explicitly authorized such action through either a formal declaration of war or specific statutory authorization for the use of military force (AUMF).

The congressional website noted that the resolution specifically demanded the cessation of U.S. military hostilities against Iran without proper congressional authorization. This legislative effort followed last Sunday's pre-dawn U.S. airstrikes against three Iranian nuclear facilities at Fordow, Natanz, and Isfahan.
