He Graduated From Caltech. He Made Video Games. Then He Charged Through a Security Checkpoint at the White House Correspondents’ Dinner Carrying a Shotgun, a Handgun, and Knives.

WASHINGTON / TORRANCE, April 26, 2026 —

Key Takeaways

• Cole Tomas Allen, 31, of Torrance, California — identified as the gunman who charged a security checkpoint at the White House Correspondents’ Dinner Saturday night — is a mechanical engineering graduate of the California Institute of Technology and a computer science master’s degree holder who worked as a part-time tutor and developed indie video games.
• Allen was armed with a shotgun, a handgun, and multiple knives when he rushed the security checkpoint at 8:36 PM at the Washington Hilton. He exchanged gunfire with law enforcement before being tackled to the ground. A Secret Service officer was struck in the bulletproof vest but was released from the hospital. No other injuries were reported.
• Allen has been charged with two counts of using a firearm during a crime of violence and one count of assault on a federal officer using a dangerous weapon, with acting U.S. Attorney for Washington Jeanine Pirro stating he was “intent on doing as much harm and as much damage as he could.” Additional charges are expected.

The Night It Happened

At 8:36 PM on Saturday, April 25, the annual White House Correspondents’ Association dinner was underway in the main ballroom of the Washington Hilton. President Trump — attending the event for the first time as a sitting president, accompanied by First Lady Melania Trump — was seated at the head of the room along with Vice President JD Vance and senior cabinet members. The ballroom held hundreds of journalists, White House staff, and guests gathered for an evening that had been billed as a historic return to the tradition Trump had abandoned throughout his first term.

Cole Allen charged through a security checkpoint at the hotel’s entrance armed with a shotgun, a handgun, and multiple knives. He exchanged gunfire with law enforcement officers stationed at the checkpoint and ran toward the ballroom stairs. Video captured from inside showed what sounded like at least five loud bangs before Secret Service agents stormed the stage, surrounding Trump and Vance and rapidly moving both off the podium. Attendees ducked under tables. A voice could be heard shouting: “Get down.”

Allen was tackled to the ground before reaching the ballroom. A Secret Service officer was struck in the bulletproof vest — the vest absorbed the round — and was released from the hospital later that night. Allen was not injured. No other casualties were reported.

Who Cole Allen Is

Allen graduated from Caltech — one of the most selective scientific universities in the United States — in 2017 with a degree in mechanical engineering. During his undergraduate years, he was featured in a local news report for developing a prototype emergency brake for wheelchairs. He also completed a summer fellowship at NASA’s Jet Propulsion Laboratory, where he said he contributed to astrophysics research and began developing a physics-based space combat game called “First Law.”

After graduating, Allen spent a year as a mechanical engineer before shifting to independent video game development. His published game, “Bohrdom,” is described on the Steam platform as a skill-based, non-violent asymmetrical fighting game. His LinkedIn profile shows he was working on a second game at the time of the attack. He also worked part-time at C2 Education, a test prep and tutoring company, where he was named teacher of the month in December 2024.

No motive has been publicly established. Acting Attorney General Todd Blanche told CNN that Allen appeared to be targeting Trump administration officials specifically. Investigators have said they believe Allen acted alone. The FBI assembled outside a home linked to Allen in Torrance on Saturday night, establishing a police perimeter while the investigation continued.

How He Got as Close as He Did

The security infrastructure around a White House Correspondents’ Dinner with a sitting president in attendance is among the most intensive of any civilian event in Washington. The venue is swept in advance. Attendees are vetted. The Secret Service operates a layered perimeter. Law enforcement from multiple agencies is present inside and outside the building.

Allen did not breach those layers. He was stopped at a security checkpoint — the outer perimeter — before reaching the ballroom. Metropolitan Police Department interim chief Jeff Carroll described the sequence as the suspect charging the checkpoint aggressively with multiple weapons, exchanging fire with officers stationed there, and being subdued before he could proceed further.

The question being examined Sunday is how Allen arrived at the Washington Hilton with a shotgun, a handgun, and multiple knives — and what drew him to the event on that specific night. Those are questions the FBI’s investigation will answer in the days ahead. What the response demonstrated is that the outer perimeter held. The deeper question — whether a better-prepared or more sophisticated attacker could have done more — is now being examined at the highest levels of the Secret Service.

The Second Time in Two Years

This is the second major security incident involving President Trump in less than two years. In July 2024, a gunman opened fire from a rooftop during a campaign rally in Butler, Pennsylvania, wounding Trump before being shot and killed by Secret Service agents. That incident triggered a full internal review of the agency’s protective protocols, leadership changes at the director level, and significant procedural reforms.

Saturday’s attack — stopped at the outer checkpoint rather than inside the venue — will be measured against those reforms. The fact that the Secret Service officer struck by gunfire was wearing a vest that stopped the round, and that no civilians were injured, will be cited as evidence that the revised protocols functioned. Critics will ask why a man carrying a shotgun, a handgun, and knives was able to initiate an exchange of gunfire at a presidential event at all.

Trump, speaking from the White House briefing room after returning from the venue, described Allen as a “lone wolf” and a “very sick person” and urged the country to resolve differences peacefully. He later posted on Truth Social that he “held it together for all of us.” The evening he had called historic — the president returning to the correspondents’ dinner — ended in evacuation, gunfire, and a federal criminal complaint filed before midnight.
