Ex-President George H. W. Bush in Intensive Care

HOUSTON (AP) -

Former president George H. W. Bush is being treated in the intensive care unit at a Houston hospital after suffering “a series of setbacks,” including a stubborn fever, his spokesman said.

In a brief email Wednesday, Jim McGrath, Bush’s spokesman in Houston, said the 88-year-old former leader had been admitted Sunday to the ICU at Methodist Hospital. McGrath said Bush, the oldest living former U.S. president, was alert and talking to medical staff.

He said doctors are cautiously optimistic about Bush’s treatment and that the former president “remains in guarded condition.” He said Bush was surrounded by family.

Early Thursday, McGrath told The Associated Press he had no new information on Bush’s condition and that he would release another statement “when events warrant it.”

Bush has been hospitalized since Nov. 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.

Bush and his wife live in Houston during the winter and spend their summers at a home in Kennebunkport, Maine.

The former president was a naval aviator in World War II, at one point the youngest in the Navy, and was shot down over the Pacific. He has skydived on at least three of his birthdays since leaving the White House in 1992.

He suffers from a form of Parkinson’s disease and in recent years has used a wheelchair to get around.
