The gunman who opened fire outside the main ballroom of the White House correspondents’ dinner is currently believed to be a guest at the Washington Hilton, the hotel where the event was being held.

On Saturday night, a gunman charged a security checkpoint and shot a Secret Service agent in the lobby of the hotel, before being apprehended. The shooting led to Trump administration officials and their families to be frantically escorted out of the ballroom, as well as thousands of attendees taking cover below tables. The annual dinner was later canceled and will be rescheduled.
