WASHINGTON, D.C. — Federal investigators have linked a buckshot pellet recovered from a Secret Service agent's bulletproof vest to Cole Tomas Allen, a 31-year-old from Torrance, Calif., who allegedly fired a shotgun at the agent during the White House Correspondents' Dinner on April 25 at the Washington Hilton in Washington, D.C. Allen has been charged with attempted assassination, discharging a firearm during a crime of violence, and illegally transporting guns and ammunition across state lines.

Allen allegedly ran through a security checkpoint at the hotel and fired the shotgun at the agent while the dinner was underway. U.S. Attorney for the District of Columbia Jeanine Pirro argued that President Trump was Allen's intended target and said Allen tracked the president's movements at the hotel using his phone in the lead-up to the shooting.

"We now can establish that a pellet that came from the buckshot from the defendant's Mossberg pump-action shotgun was intertwined with the fiber of the vest of the Secret Service officer," Pirro said. "It is definitively his bullet."

"He hit at that Secret Service agent. He had every intention to kill him and anyone who got in his way on his way to killing the president of the United States," she said.

Acting U.S. Attorney General Todd Blanche said additional developments in the case were expected in the coming days.

"I expect in the next week or so, there will be more information coming out. Obviously, assuming the investigation moves forward, there will be an indictment forthcoming. And all that is typical of what happens," Blanche said.
