Cole Tomas Allen, 31, aimed to target Trump officials at the White House Correspondents' Dinner, according to sources. He was stopped at the security checkpoint outside the event.
The Secret Service Deputy Director stated that Allen underestimated their protective capabilities and was stopped at first contact.
The FBI raided Allen's home in Los Angeles, surrounding the property and conducting an initial entry into the residence.
The White House Correspondents' Dinner was abruptly interrupted when a gunman breached security and opened fire, prompting the evacuation of President Trump and other high-ranking officials.
