Authorities say Cole Tomas Allen, a 31-year-old California man, is accused of attempting a politically motivated attack at the White House Correspondents’ Association dinner on April 25, after sending writings to family expressing grievances against the 47th president’s administration. Investigators believe Allen acted alone, legally acquired multiple weapons, and intended to target administration officials before being subdued by security, prompting a chaotic scene and the evacuation of the president, who was unharmed.
