HOUSTON (AP) — One by one, speakers took the stage at the National Rifle Association’s annual convention and denounced the massacre of 19 students and two teachers at an elementary school across the state. And one by one, they insisted that changing U.S. gun laws or further restricting access to firearms was not the answer. The gathering comes just three days after the shooting in Uvalde. Hundreds of protesters shouted their anger at the NRA outside the meeting. In remarks to the group, former President Donald Trump calls for an overhaul of school security and the U.S. approach to mental health problems while dismissing calls to disarm gun owners.
