Testimony of witnesses before a congressional ethics committee investigating House Speaker Jim Wright have been so secret that some top committee staff members do not know about them, the Fort Worth Star-Telegram reported. One witness is Carlos Moore, publisher of a book at the center of one of the allegations against Wright. Moore agreed to publish “Reflections of a Public Man,” which paid Wright an unusually high royalty rate that netted him $55,000. The sessions with witnesses have been held almost daily but at various Capitol Hill sites that are changed frequently to stymie reporters, the paper said. The committee is investigating six counts against Wright.
