A Donald Trump supporter, linked to death threats made to U.S. president Joe Biden, vice president Kamala Harris, and Manhattan district attorney Alvin Bragg, was killed during an FBI raid on his home in Provo, Utah.

Craig Robertson, 75, was first identified in the New York Post as the suspect, according to whom he made social-media posts describing himself as a “MAGA TRUMPER.”

“The FBI takes all shooting incidents involving our agents or task force members seriously,” an agency statement given to the Post on Wednesday noted. In accordance with FBI policy, the shooting incident is under review by the FBI’s Inspection Division.”
