A 31-year-old Southern California resident identified as Cole Thomas Allen opened fire at security during the White House Correspondents' Association dinner in Washington on Saturday, authorities confirmed. Allen, from Torrance, California, rushed a security checkpoint armed with a shotgun, handgun and multiple knives as he moved toward the ballroom where the annual event was underway.
Metropolitan Police Interim Chief Jeff Carroll said Allen exchanged gunfire with law enforcement before officers tackled him to the ground. No injuries to the suspect were reported. A Secret Service officer was struck in his bulletproof vest but survived and was discharged from a local hospital early Sunday.
The attack occurred during Trump's first attendance at the dinner since becoming president. Video captured at least five loud bangs before armed officers rushed the president, first lady Melania Trump, Vice President JD Vance and others from the ballroom. Trump later described the moment from the White House briefing room, saying he initially thought it was a tray dropping. "Melania was very cognizant, I think, of what happened," he said. "She was saying, 'That's a bad noise.'"
Allen's motive remains unclear. Federal authorities said he has no criminal record and was not previously flagged by law enforcement in Washington. His background suggests an accomplished but enigmatic figure. According to his LinkedIn profile, he graduated from the California Institute of Technology in 2017 with a bachelor's degree in mechanical engineering. Caltech confirmed the enrollment record. He later earned a master's degree in computer science from California State University, Dominguez Hills in May 2025.
After his initial post-graduation position as a mechanical engineer, Allen transitioned to independent video game development and part-time teaching at a college preparation company. A former high school volleyball teammate from Pacific Lutheran High School in Gardena, California, described Allen as a "borderline genius" and "super stable." The teammate, speaking anonymously, recalled Allen's exceptional intellectual abilities and wide-ranging knowledge across subjects including coding, writing and diverse academic fields.
"Other people study hard," the former teammate told NBC News. "He didn't have to study. It would just come to him. He was really, really smart." The teammate expressed shock at Allen's involvement in the attack, characterizing him as "probably the most gentle person on the team."
U.S. Attorney for Washington Jeanine Pirro announced initial charges including two counts of using a firearm during a crime of violence and assault on a federal officer using a dangerous weapon. She indicated "many more charges" will follow.
Investigators served a search warrant at a Torrance residence believed associated with Allen late Saturday. The FBI and Secret Service worked the scene as part of the ongoing investigation. Allen is expected to be arraigned Monday in federal court.
Torrance, located about 15 miles southwest of downtown Los Angeles in California's South Bay region, is a city of approximately 140,000 residents.
Author Sarah Mitchell: "A Caltech mechanical engineer turned coder pulling a gun at the president's table doesn't fit any obvious pattern, which is exactly what makes this moment so unsettling."
