In this Feb. 22, 2018, photo, President Donald Trump speaks during a meeting with state and local officials to discuss school safety in the Roosevelt Room of the White House in Washington. Trump could face a backlash from gun rights advocates who fear he’s strayed from his pledge to be a champion for the Second Amendment by voicing support for gun control measures in the wake of the deadly school shooting in Florida.
