The suspect in the White House Correspondents’ Association dinner shooting “definitively” fired the bullet that hit a Secret Service agent’s vest during the incident, U.S. Attorney for the District of Columbia Jeanine Pirro said.

“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.”
