US Senate votes to halt Iran war despite Trump’s push for peace deal

The US Senate adopted a resolution on Tuesday directing the president to remove military forces from the conflict with Iran, a significant rebuke to Donald Trump and a strong message that the war lacks support in Congress. Democrats have repeatedly forced votes to limit Trump’s war powers in both the House and the Senate — a campaign that has gradually picked up more GOP support in recent weeks, drawing the president’s ire. The resolution was passed by a 50-48 vote, with four Republicans — Susan Collins of Maine, Lisa Murkowski of Alaska, Bill Cassidy of Louisiana and Rand Paul of Kentucky — breaking ranks with their party to vote in favour of the measure. John Fetterman of Pennsylvania was the sole Democrat to vote against it.

The resolution had earlier passed the US House of Representatives by a vote of 215-208, with four Republicans joining Democrats in supporting the war powers measure. The Republicans were Thomas Massie of Kentucky, Brian Fitzpatrick of Pennsylvania, Warren Davidson of Ohio and Tom Barrett of Michigan. This is the tenth time since the beginning of the year that the Senate has passed a resolution seeking to limit Trump's war powers over Iran that requires the US to cease hostilities against Iran unless Congress votes to authorise further attacks. While the resolution is largely symbolic and does not carry the force of law, it reflects growing concern among a number of Republican lawmakers in both the House and the Senate over the conflict with Iran and the agreement Trump has reached to end it.
A White House official dismissed the Senate vote, saying the resolution “has no significance” and blaming the measure’s adoption on “Republican absences.” “Concurrent resolutions do not go to the president and have no force of law,” the official said.
