President Trump and Cabinet officials were quickly removed out of the room by Secret Service agents.
Wolf Blitzer of CNN was one among the witnesses; he was outside the ballroom when he seen a gunman firing a few feet away.
As police descended upon the area, he and scores of other people sought shelter. While wearing protective gear, a US Secret Service agent was shot and hit.
President Trump later claimed to have personally spoken with the agent, who was admitted to the hospital, and that they were in “great shape” because of their bulletproof vest.
No one else was hurt, according to DC Mayor Muriel Bowser. President Trump made his first public remarks at 9:17 p.m., announcing on Truth Social that the accused gunman “has been apprehended.”
