U.S. District Senior Judge Jack T. Camp entered guilty pleas Friday to a federal drug felony and two misdemeanors associated with his arrest last month after a string of liaisons with a stripper and prostitute who also was a convicted drug felon and a confidential informant for the FBI.

Camp, who was arrested with two guns in his possession while abetting a drug purchase, was not charged with any gun-related offenses. He also has agreed to help the government defend any challenges to cases he presided over as a judge. Under the plea agreement, Camp likely faces four to 10 months in prison and a fine of as much as $10,000.
