(Provo, UT) — Former President Donald Trump’s Truth Social media platform tipped off the FBI in March about a Provo man who made online threats to President Biden and who was shot by FBI agents this week. Agents shot and killed Craig Robertson outside his Provo home on Wednesday when they tried to arrest him for threatening to kill Biden as he visited Utah Wednesday and Thursday. Truth Social notified the FBI in March after Robertson posted a threat to kill Manhattan District Attorney Alvin Bragg, who is prosecuting Trump over an alleged hush money payment to adult film star Stormy Daniels. The 75-year-old Robertson was armed when FBI agents came to his home, pointed the weapon at agents, and didn’t respond to their commands before they shot him, a senior official told NBC.
