George H.W. Bush in intensive care with "stubborn fever"

Bush was in guarded condition and on a liquid diet that took effect with his transfer to the ICU, but McGrath could not offer more details about the reasons for the liquid diet.

Doctors were initially treating him for bronchitis and a lingering cough. More recently he had been undergoing physical therapy in preparation for returning home. He developed a fever mid- to late last week and began experiencing other complications that McGrath described as “a series of setbacks.”
