As students across the United States today join a nationwide school walkout to demand lawmakers take action on gun control, we go to Tennessee, where Republicans are trying to expel three Democratic lawmakers for supporting student-led gun control protests at the state Capitol after last week’s school shooting in Nashville. “We’re demanding that lawmakers hear that we can’t be ignored anymore,” says Ezri Tyler, a student at Vanderbilt University in Nashville and a national organizer for March for Our Lives. “This is authoritarianism,” Tennessee state Representative Justin Jones says of attempts to remove him. “This is an assault on our democracy.”
