But administration officials argued yesterday that Congress has no power to force a U.S. attorney to pursue contempt charges in cases, such as the prosecutor firings, in which the president has declared that testimony or documents are protected from release by executive privilege. Officials pointed to a Justice Department legal opinion during the Reagan administration, which made the same argument in a case that was never resolved by the courts.
