Cole Tomas Allen, the 31-year-old suspect accused of attempting to enter the White House Correspondents’ Association dinner on Saturday night while carrying multiple firearms, was formally charged Monday with attempting to assassinate President Donald Trump.

Allen, who was making his first court appearance, is also facing two federal gun charges, including interstate transportation of weapons and discharge of a firearm during a violent crime, according to a court filing. He did not enter a plea and will reappear in court in three days to determine if he will remain in detention, according to NBC News.

Authorities identified Allen, a California resident, as the suspect arrested Saturday night. They said he planned to target high-profile members of the administration during the annual dinner, a gathering of thousands of journalists, administration officials and politicians that took place at the Washington Hilton.

During the brief arraignment Monday, Assistant U.S. Attorney Jocelyn Ballantine said Allen was found to have a .38-caliber semi-automatic pistol, a 12-gauge pump-action shotgun and three knives, according to NBC News.

A Secret Service agent was shot once in the chest during the incident but has been released from the hospital. Acting Attorney General Todd Blanche said Allen had discharged his shotgun but wouldn’t confirm if he had hit the agent.

Allen will face additional charges, U.S. Attorney Jeanine Pirro said during a press conference Monday afternoon.

Authorities apprehended Allen after he ran through a metal detector at a security checkpoint on the floor above the annual gala that Trump, Vice President JD Vance and several Cabinet officials attended.

Blanche said on Monday that on April 6, Allen had made a hotel reservation for April 24-26. He traveled from Los Angeles to Chicago and then to D.C. by train, where there are fewer security restrictions than on flights.

Blanche blamed the news media when asked to describe the current political threat environment.

“Many people in this room, if we’re going to be honest about it, have done it as well; they’re just as guilty as a lot of people on X,” he said. “When you have reporters — when you have media just being overly critical and calling the president horrible names for no reason and without evidence, without proof, it shouldn’t surprise us that this type of rhetoric takes place.”

White House press secretary Karoline Leavitt also placed blame on liberal media personalities and Democrats on Monday. The comments from Blanche and Leavitt deviated from Trump’s description of the goal of Saturday’s dinner as unifying for journalists, Republicans and Democrats.

“It was, in one way, a very beautiful, a very beautiful thing to see,” Trump said during a White House press conference shortly after the attack.
