Cole Tomas Allen has been formally charged in federal court with attempting to assassinate Donald Trump following a violent security breach at a high-profile Washington event, prosecutors confirmed during a court hearing on Monday.
Court Hears Serious Federal Charges
During proceedings, federal prosecutors alleged that Allen attempted to breach security at an event attended by political leaders and journalists, leading to a confrontation with a Secret Service agent.

Prosecutor Jocelyn Ballantine told the court that Allen “attempted to assassinate the president of the United States,” marking one of the most serious accusations presented in the case so far.
Allen, who appeared in court wearing a blue prison jumpsuit, has not yet entered a formal plea.
Detention Ordered by Judge
Matthew Sharbaugh ordered Allen to remain in federal custody as the case proceeds, citing the severity of the allegations and potential security risks.
A follow-up hearing regarding continued detention has been scheduled for later this week.
Alleged Manifesto Under Investigation
According to prosecutors, Allen reportedly left behind a manifesto with family members in which he referred to himself as the “Friendly Federal Assassin” and outlined intentions to target senior administration officials.

Authorities say the document is now a key part of the ongoing investigation into motive and planning.
Authorities Link Case to Broader Threat Concerns
The case follows a reported security incident at the White House Correspondents’ Association dinner, where Allen allegedly attempted to breach security before being apprehended.
Officials described the event as a serious threat to national security, involving a Secret Service agent who was injured during the confrontation.
White House Reaction
White House press secretary Karoline Leavitt described the incident as part of a broader pattern of threats targeting the president, referencing past alleged assassination attempts.
Authorities have not publicly confirmed all details surrounding those earlier incidents.
Ongoing Federal Investigation
Allen, who reportedly holds a master’s degree in computer science, remains in custody as federal investigators continue examining his background, digital activity, and travel history.
The case is expected to proceed in federal court over the coming weeks, with additional hearings scheduled as prosecutors build their case.
