The suspect, identified as 31-year-old Cole Tomas Allen, is accused of attempting to storm the ballroom at the White House Correspondents' Association dinner with guns and knives. His family had raised concerns with law enforcement before the event, according to President Donald Trump. The suspect's brother contacted police in Connecticut about the manifesto, which was discovered shortly before 11 p.m. The Justice Department confirmed that Allen had planned to target members of the administration, likely including the president. The incident occurred shortly after the event started, leading to a cancellation of the event and a significant disruption. The gunman was taken into custody and is expected to face multiple charges.
