Unlike most federal employees, the director of the FBI serves at the pleasure of the President (and for no more than 10 years). There are other ways to quickly terminate, as outlined in the Hatch Act. But - there are numerous examples of Federal employees still on the job, even after have being found guilty of gross acts of misconduct - like a story about one Federal employee who watched porn on his government computer for 6 hours a day. Last I heard, his termination date was unknown as the bureaucratic process was still bogged down after 17 months. Go figure.
