Federal authorities are investigating menacing phone calls and other messages directed at Michael Fanone, a former D.C. police officer who was seriously hurt defending the Capitol from rioters on Jan. 6, 2021, and has since become an outspoken critic of former president Donald Trump, according to Fanone and another person familiar with the matter.Fanone said a prosecutor with the U.S. attorney’s office in D.C. told him Thursday that the FBI had launched an inquiry into the communications he received, after he forwarded a recording of call in which someone told him: “The world would be a better place if you were hit by a fast moving bus tomorrow.” That call came hours after Fanone, who was beaten and shocked with a stun device until he lost consciousness and suffered a heart attack during the Jan. 6 riot, testified at a sentencing hearing for one his attackers Tuesday in federal court.A judge sentenced Fanone’s assailant to seven years and two months in prison after Fanone told the man, “I hope you suffer.” Fanone said he forwarded a recording of the menacing call, which came from a number in Delray Beach, Fla., to a federal prosecutor, who texted him: “Ok, got it.A person familiar with the matter, speaking on the condition of anonymity because they were not authorized to discuss the open case, confirmed the investigation.Timothy Barber, a spokesman for the U.S. Capitol Police, said Fanone has not contacted department officials “to voice safety concerns.” In a statement, Barber said: “We are proud of all the officers who heroically defended the Capitol and would gladly listen to his concerns.” Barber also said Capitol Police were not aware Penn had planned to attend the hearing with Fanone, “so when the arrival created a frenzy, officers ensured all of the guests and journalists could safely move around.” Fanone denied Penn’s visit caused a frenzy in the hearing room."
