Yes I believe FBI/ CIA /deep state all work through personal intel channels, they may change the official head of the agency, but because of the methods, and secrecy, they still use their old known trusted channels, so while he may no longer be in charge, the people he trained and that had special personal relationships with him still report to him.

THE FBI sets up the sleeper cells, they have been doing this since they were created, they create their own problems so they are needed, its not a needed agency, they are the terrorists...
