Republicans at the annual Conservative Political Action Conference largely rallied behind U.S. strikes on Iran on Thursday, backing President Donald Trump on an issue that has dented his wider approval ratings and could jeopardize the party's prospects in the November midterm elections. Speakers ranging from a prominent evangelist to a former Trump adviser and Iranian political activists took to the stage at the conservative gathering in Grapevine, Texas, to argue the moral case for the war before supporters of Trump's Make America Great Again movement.
