Former FBI spy hunter sentenced to prison for aiding Russian oligarch

Former FBI special agent Charles McGonigal has been sentenced to over four years in prison for providing information to a Russian oligarch, in violation of US sanctions. McGonigal, one of the highest-ranking FBI officials to be convicted of a crime, supplied information to Oleg Deripaska to help him sink a business rival. He received a payment of $17,500, which was laundered through various accounts. McGonigal's actions were deemed to have jeopardized national security, and he faces a second sentencing for hiding payments from a former Albanian intelligence officer.
