Former President George H.W. Bush was admitted to a hospital intensive care unit after " a series of setbacks including a persistent fever," but is alert and talking to medical staff, his spokesman said.
Jim McGrath, Bush's spokesman in Houston, said in a brief email Wednesday that Bush was admitted to the ICU at Methodist Hospital on Sunday. He said doctors are cautiously optimistic about his treatment and that the former president "remains in guarded condition." No other details were released about his medical condition, but McGrath said Bush is surrounded by family. (AP)
