Former US President George H.W. Bush has been admitted to the intensive care unit at a Houston hospital.
Jim McGrath, Bush's spokesman in Houston, said that Bush was admitted to the ICU at Methodist Hospital on Sunday following a series of setbacks including a persistent fever.
He said doctors are cautiously optimistic about his treatment and that the former president "remains in guarded condition."
The 88-year-old has been hospitalised since November 23, when he was admitted for a lingering cough related to bronchitis after having been in and out of the hospital for complications related to the illness.
