Inside Washington

Senior Administration sources are speculating that WARREN CHRISTOPHER, who has come under fire as Secretary of State, will be renamed a senior adviser to the President by the end of the year, and Lloyd Bentsen will take over at State. Then, goes this scenario, White House chief of staff Mack McLarty will assume Bentsen's Treasury Secretary post, and deputy chief of staff Harold Ickes will fill McLarty's job. Christopher is said to be so insecure that his staff is keeping a distance between Bentsen and him.
