HOUSTON (AP) - Former first lady Barbara Bush is still in a Houston hospital after a series of routine tests over the weekend.
Family spokeswoman Jean Becker said Monday that the Bushes are hoping she can come home later in the day, but no timetable has been set.
Becker said the 84-year-old Bush has not been diagnosed with anything and doctors aren't looking for anything specific. Former President George H.W. Bush drove his wife to Methodist Hospital on Saturday morning.
Becker said earlier that the former first lady hadn't been feeling well for about a week. Mrs. Bush had heart surgery in March 2009 for a severe narrowing of the main heart valve.
