On Tuesday, June 16, the United States Senate rejected a Democratic resolution aimed at limiting the war powers of US President Donald Trump regarding the Islamic Republic by a razor-thin margin of 47 votes in favor and 48 against.

The vote took place shortly after Trump announced that a preliminary agreement had been reached with Tehran to end months of conflict. However, the details of this agreement remain undisclosed, prompting demands from lawmakers to review the text in Congress.

According to a report by CBS News, the resolution, introduced by Democratic Senator Raphael Warnock, aimed to require the President to withdraw US armed forces from any military hostilities against Iran unless Congress issued a declaration of war or specific authorization for the use of military force. Supporters of the bill argued that, without such authorization, continuing any operations contradicts the legislative branch’s oversight role.

According to the same report, the White House, citing its own legal interpretations, considers the War Powers Resolution of 1973 incompatible with the Constitution. It argues that the law’s 60-day deadline to halt the use of military force was paused following the ceasefire declaration in early April. Democrats object to this interpretation, asserting that the administration must provide the details of the preliminary agreement with Tehran to Congress to allow for oversight and legal assessment.
