National security adviser Condoleezza Rice returned home Saturday after a one-night hospital stay where she was treated for noncancerous growths in her uterus. «She's out of the hospital and doing well,» said White House spokesman Fred Jones. Rice had uterine fibroid embolization at Georgetown University Hospital on Friday. Rice could return to work as early as Monday, Jones said. President George W. Bush announced on Tuesday that Rice, 50, will succeed Secretary of State Colin Powell. Her nomination must be confirmed by the Senate.
