He told CNN he and others hid in a classroom after shots rang out during his AP environmental science class. The chief of the school's student television station, he flipped on a camera and recorded a message in a darkened room. There, he described the situation in real-time as "life or death" and later told NBC he recorded the message in the event he and others died.

“People get used to what’s going on and that’s not OK," he said on MSNBC. "We’re habituating to this and what happens when we do that is children are dying and they will continue to die unless we stop it. Stand up and take action.”

Peering into the CNN camera, he gave specific directions to Congress and lawmakers.

"Any action at this point, instead of complete stagnancy and blaming the other side of the political aisle, would be a step in the right direction," he said. "And working together to save these children’s lives is what this country needs.”
