A California man accused of attempting to assassinate President Donald Trump at the White House Correspondents' Dinner agreed to remain in custody Thursday as federal prosecutors continue gathering evidence in the case, according to reporting by the [Nebraska Examiner](https://nebraskaexaminer.com/2026/04/30/repub/suspect-in-washington-press-dinner-attack-to-remain-detained-in-d-c-jail/). Cole Tomas Allen, 31, of Torrance, California, appeared before a federal magistrate judge in Washington, D.C., five days after he allegedly rushed a security checkpoint outside the Washington Hilton ballroom where Trump, Vice President JD Vance and Cabinet members were attending the April 25 dinner.

Allen faces charges of attempting to assassinate the president, interstate transportation of a firearm with intent to commit a felony, and discharge of a firearm during a crime of violence. The attempted assassination charge carries a potential sentence of life in prison. A Secret Service agent was struck by gunfire during the incident but was protected by a bulletproof vest. Trump, first lady Melania Trump and Cabinet members safely evacuated the ballroom.

During Thursday's hearing, prosecutors indicated they were examining ballistics evidence to prove a single shot fired at the Secret Service agent came from Allen's weapon. U.S. Attorney Jeanine Pirro said the government's investigation and crime scene analysis remain ongoing.

Allen's public defenders protested conditions of his detention at the D.C. jail, citing [Sixth Amendment concerns about attorney-client communications.](https://www.washingtonpost.com/politics/2026/04/25/trump-whcd-evacuation-live-updates/) A federal magistrate judge ordered jail officials to permit unrestricted visits between the defendant and his attorneys. A preliminary hearing is scheduled for May 11.
