A former top FBI counterintelligence official - in fact, the guy who received the tip that supposedly kicked off the Trump-Russia investigation - has been arrested and charged with violating US sanctions on Russia by taking secret payments from a Russian oligarch in order to investigate another oligarch.
Federal prosecutors in Manhattan charged Charles McGonigal, former special agent in charge of the FBI's New York counterintelligence desk, with taking secret payments from Oleg V. Deripaska - which violated US sanctions by agreeing to help the Russian billionaire, who himself was indicted last year on sanctions charges. McGonical notably retired in 2018.
During his days in counterintelligence, McGonical was responsible for supervising and participating in investigations of Russian oligarchs, including Deripaska.
The indictment unsealed in Federal District Court in Manhattan on Monday charges the former F.B.I. official, Mr. McGonigal, with one count of violating U.S. sanctions, one count of money laundering and two conspiracy counts. -NY Times
