A former top FBI official was charged on Monday with working for sanctioned Russian oligarch Oleg Deripaska, as U.S. prosecutors ramp up efforts to enforce sanctions on Russian officials and police their alleged enablers. Charles McGonigal, who led the FBI’s counterintelligence division in New York before retiring in 2018, pleaded not guilty to four criminal counts including sanctions violations and money laundering at a hearing in Manhattan federal court.
