Gruber is the father of Justin Gruber, who was hiding in a closet during the shooting last week at Marjory Stoneman Douglas High School in Parkland, Fla.

The listening session was made up of Stoneman Douglas students, as well as parents of victims from the 2012 Sandy Hook Elementary School shooting and the 1999 Columbine High School shooting.

Trump opened the session promising to get tough on background checks.

"We're going to be very strong on background checks," the president said.

"It’s not going to be talk like it has been in the past. It’s been going on too long. Too many instances, and were going to get it done."
