The Republican-led US House of Representatives voted on Thursday to direct President Donald Trump to end the use of military force against Iran unless Congress approves. The resolution passed 214-208, with four Republicans joining Democrats in support. The measure was largely symbolic, as similar resolutions in recent months have not led to a change in policy. Introduced by Democratic Representative Pramila Jayapal, the resolution seeks to assert Congress's war powers. Meanwhile, the Senate was expected to vote on a similar war powers resolution, but Republican senators blocked it, with Senator Bill Cassidy casting a decisive vote. The moves reflect ongoing tensions between Congress and the president over the conflict with Iran.
