Bush's spokesman, Jim McGrath, told the AP in an email Wednesday that Bush, 88, had been admitted Sunday to the ICU at Methodist Hospital. McGrath noted that the former President was alert and talking to medical staff. Doctors are cautiously optimistic about his treatment and Bush "remains in guarded condition," McGrath said, adding that Bush was surrounded by family members.
Bush, who is the oldest living former U.S. president, has been hospitalized since Nov. 23 when he was admitted for a cough related to bronchitis. Prior to his stay, Bush had been in and out for the hospital for complications related to the illness. Doctors put him on a liquids-only diet Wednesday following "a series of setbacks" and a worsening fever.
