US Senate Signals Intensifying Opposition to Trump’s War in Iran

Senate Advances War Powers Measure After GOP’s Cassidy Switches Sides

A Senate Republican spurned by President Donald Trump joined Senate Democrats to handcuff his war powers in Iran and provided the key vote to advance a war powers resolution through a key hurdle.

Trump notified Congress about the use of military force against Iran on March 2, starting a 60-day clock under the War Powers Resolution of 1973 requiring him to seek congressional authorization or end U.S. military involvement in the conflict.

Bill Cassidy — fresh off a primary election loss in which Trump endorsed his opponent — switched sides to deliver a crucial vote to pass the legislation.
