FILE-This June 14, 2016 file photo shows Dr. Chadwick Smith, one of the doctors that treated victims of the Pulse nightclub shooting, as he describes how he and others called for reinforcements that night, at a news conference at the Orlando Regional Medical Center, in Orlando, Fla. Smith is used to confronting human suffering head-on in the operating room. But the sheer number of victims that night, 49 dead, 53 wounded, and the flood of relatives to the hospital left its mark on even a veteran like Smith. (AP Photo/John Raoux, File)
