Former first lady Barbara Bush still in hospital
Former US first lady Barbara Bush (above) remains hospitalised in Houston, where she is undergoing what a family spokeswoman described as routine tests.
Spokeswoman Jean Becker said yesterday that Mrs Bush has not been diagnosed with anything and doctors are not looking for anything specific.
Former president George HW Bush drove his wife to hospital on Saturday morning. Mrs Bush underwent heart surgery in March 2009 for a severe narrowing of the main heart valve.
