"One of the top FBI's Russian spy catcher is indicted: The charges against McGonigal alarmed his former colleagues in part because of his depth of knowledge of so many elements of U.S. espionage. McGonigal was an expert on Russian intelligence activities targeting the United States, as well as U.S. efforts to recruit Russian spies, said several former intelligence officials who worked with him and spoke on the condition of anonymity to describe sensitive matters.
McGonigal has not been charged with espionage, but the former officials who worked with him said his knowledge and experience would have put him at high risk of being recruited by a foreign government.
One former official noted that McGonigal was in charge of an investigation into why numerous individuals in China who were spying for the United States were arrested and taken out of commission. As part of that investigation, McGonigal would have known details about the covert systems that the CIA used to communicate with its agents, the former official said. Those systems are believed to have played a central role in exposing the agents to government authorities."
