A 31-year-old California man, Cole Tomas Allen, appeared in a Washington federal court on Monday, facing charges for the attempted assassination of President Donald Trump.
The incident occurred during the White House Correspondents’ Association Dinner, a high-profile gathering of journalists and politicians.
Prosecutors revealed that Allen, who holds a master’s degree in computer science, travelled from Torrance to the capital by train and was armed with a 12-gauge shotgun and three knives at the time of his arrest.

In the document, he reportedly referred to himself as the “Friendly Federal Assassin” and outlined intentions to target senior members of the Trump administration.
The shooting caused immediate chaos in the ballroom, forcing attendees to seek cover and prompting security to rush the president off stage as law enforcement subdued the suspect near a security perimeter.
In addition to the assassination charge, Allen faces counts of discharging a firearm during a violent crime and illegal interstate firearm transport.

The White House has characterised the event as the third major attempt on the president’s life, sparking renewed debates over political rhetoric and the security protocols protecting high-ranking U.S. officials.
