When the Watergate scandal broke, Krogh was implicated. On November 30, 1973, Krogh pleaded guilty to federal charges of conspiring to violate Fielding's civil rights and agreed to cooperate with prosecutors. He was sentenced to six years in prison, though he served only four-and-a-half months. Krogh was disbarred by the Washington State Supreme Court in 1975. In 1977 he petitioned to be readmitted to the practice of law, based on his recognition and acceptance of his wrongdoing. This petition was rejected. Finally, in 1980, his petition was granted and he was reinstated to the practice of law.
