Republican-majority US Senate votes to curb Trump's powers in Iran war

The Republican-controlled U.S. Senate approved legislation on Tuesday aimed at ending military operations against Iran, a move that reflects growing unease over the conflict. The resolution passed with a narrow 50-48 vote, largely along party lines, with four Republicans joining Democrats in support.

This concurrent resolution, which previously cleared the House of Representatives, directs President Donald Trump to withdraw U.S. armed forces from hostilities with Iran. However, its practical impact remains uncertain as the White House argues the measure is unconstitutional and therefore not binding. Legal experts suggest the dispute may ultimately be settled in the courts.

The Senate's vote took place shortly after reports surfaced that the Pentagon is seeking an additional $80 billion to fund the ongoing war in Iran. This request would add to the White House's proposed $1.5 trillion defense budget, representing a nearly 50% increase over current fiscal year funding.

The executive branch will likely ignore it on constitutional grounds, and it’s not clear who might have standing to sue to enforce it.
