The annual gala—widely known as the “Nerd Prom”—had been underway for only about 20 minutes after the president and first lady arrived when the dramatic incident unfolded. According to federal authorities, an armed man tried to force his way through a secured checkpoint and advance toward the main ballroom before being confronted by U.S. Secret Service agents.
Investigators identified the suspect as 31-year-old Cole Tomas Allen of Torrance, California, a teacher, video game developer, and California Institute of Technology (Caltech) graduate. Officials said Allen was carrying a shotgun, a handgun, and multiple knives when he rushed the security perimeter, setting off an immediate law enforcement response.
Secret Service agents intercepted the suspect inside the hotel lobby before he could reach the crowded ballroom. A violent struggle followed, during which gunfire erupted. One Secret Service agent was struck at close range, but officials said the agent’s ballistic vest prevented fatal injuries. The wounded officer was transported to a nearby hospital and was reported to be in stable condition. Allen sustained minor injuries before being taken into federal custody.
Within moments, security teams ordered a full evacuation of the venue as heavily armed officers swept the hotel to ensure there were no additional threats. Although organizers initially considered resuming the evening’s program, the White House Correspondents’ Association ultimately canceled the event, citing ongoing security concerns. Officials say the dinner is expected to be rescheduled with significantly enhanced security measures.
