He was promoted by his boss Freeh director of the FBI. Do you think he would alert the US gov if he found a Russian spy bringing a suitcase bomb into the US from Bosnia? 1995/96
He can do nothing; he is serving a life sentence at USP Florence Admax.
He made a deal with the FBI; in return for giving his wife his government pension, he told the FBI everything that he knew. By that time, most of the FBI & CIA sources had been terminated with extreme prejudice.
FBI "He didn't tell us everything ,so didn't qualify for a lesser sentence"
20 years of seriously damaging espionage (including our agents were identified and executed) to help people like Putin grab Russian assets is not ok and should not be smoothed over. + possibly nukes on board.
