David Hogg, a student at Stoneman Douglas High School in Parkland, Florida where 17 were massacred in a shooting Wednesday, spoke directly to President Trump on CBS' "Face the Nation" Sunday. He responded to a Saturday Trump tweet blaming Democrats for not passing gun control legislation when they controlled the government during the Obama administration.

"President Trump, you control the House of Representatives, you control the Senate. You control the Executive. You haven't taken a single bill for mental health care or gun control and passed it. And that's pathetic. We've seen a government shut down. We've seen tax reform, but nothing to save our children's lives. Are you kidding me? You think now is the time to focus on the past and not the future to prevent the death of thousand of other children? You sicken me."

Another student, Cameron Kasky, addressed his senator, Marco Rubio, who said after the Parkland tragedy that shooters "will find a way to get the gun."

"It's not our job to tell you, Senator Rubio, how to protect us ... Our job is to go to school, learn and not take a bullet ... Your job to protect us and our blood is on your hands."
