Did you hear about Charles McGonigal?

I just saw an article that tells the story of Charles McGonigal. He was one of the FBI Counterintelligence agents that was pushing the Trump/Russia collusion narrative. He just got sentenced to 50 months in prison for Russia Collusion. He was apparently working with a Russian Oligarch (Oleg Deripaska)that has ties to Putin to find ways around the US sanctions against Russia. He also laundered money from his contact. Kind of interesting that his arrest was not mentioned in the news when it happened.

Does this point even more to a corrupt FBI?
