Cole Allen has been identified as the suspect in the shooting at the annual White House Correspondents Associated dinner by multiple outlets after the Saturday incident at the Washington Hilton Hotel.

Allen is expected to be arraigned on Monday on two preliminary charges that include using a firearm during a crime of violence and assault on a federal officer using a dangerous weapon, according to U.S. Attorney for the District of Columbia Jeanine Pirro.

Campaign finance records show Allen once donated $25 to a Democratic Party political action committee to back former Vice President Kamala Harris`s presidential bid, as reported by The Associated Press.

Authorities are still investigating the alleged gunman`s motive for opening fire at the annual event with President Trump and first lady Melania Trump in attendance.

Trump was the first person to formally brief reporters after the live shooter incident and ultimately shared two separate posts on Truth Social with photos of the suspected shooter with his wrists bound behind his back, shirtless and laying face down on the ground.

Allen is a 31-year-old from Torrance, California, and is a professional game designer with a master`s degree in computer science from California State University-Dominguez Hills, according to the AP.

He earned his undergraduate degree in mechanical engineering at California Institute of Technology, also known as CalTech.

Over the course of his professional career, Allen had numerous video games that allow users to shoot and attack.

One of Allen`s games known as "First Law," a 2D Newtonian physics-based platformer released on Steam in 2024.

Another one of his games labeled "Bohrdom," which Allen described as a "combination of a racing game with a bullet hell as experienced by self-propelled pinballs," per Fox News.

The Hill has not independently verified Allen`s identity. The Department of Justice and FBI did not immediately respond to requests for comment on the matter.

Allen struck one officer during the shooting at the Washington Hilton. The officer was "saved" by a bulletproof vest, according to Trump.

Allen was armed with a shotgun, a handgun and multiple knives, according to police.
