Former FBI Spy Hunter Sentenced to 4 Years for Aiding Russian Oligarch

Former top F.B.I. agent, Charles F. McGonigal, has been sentenced to over four years in prison for conspiring to launder money and violate U.S. sanctions targeting a Russian oligarch with ties to President Vladimir V. Putin. McGonigal, who served as chief of counterintelligence for the F.B.I. in New York, pleaded guilty to working on behalf of the Russian aluminum magnate, Oleg V. Deripaska, in violation of sanctions. He is one of the highest-ranking F.B.I. officials ever to be convicted of a crime. The judge emphasized the seriousness of his crimes, which endangered national security, and fined him $40,000. McGonigal also faces sentencing in a separate case in Washington, D.C.
