U.S. District Judge Peter Messitte granted Johnson a 15-day extension until Feb. 18.

Johnson’s attorney, Jeffrey Harding, said “there is nothing unusual,” about the extension.

Ed Ross, a spokesman for the federal Bureau of Prisons, said such delays often occur, but is checking further.

Johnson (D), who Harding said has been found to have some form of Parkinson’s, has been undergoing medical treatment to ascertain what type it is.

Assistant U. S. Attorney James A. Crowell IV opposed the extension for Johnson.

Johnson’s wife Leslie, a former member of the Prince George’s County Council, is scheduled to report to prison on March 9 for a one-year term.

She pleaded guilty to evidence tampering and destruction of evidence after being arrested with $79,600 in her underwear and being overheard of a federal wiretap speaking with her husband about plans to tear up and flush a $100,000 check from Laurel developer Mirza Baig, a physician.
