Former President Bush, 90, To Spend Fourth Night In Houston Hospital

(Reuters) - Doctors in Houston have decided to keep former U.S. President George H.W. Bush in the hospital for a fourth night since his bout with shortness of breath, though his condition has improved and he "remains in high spirits," his spokesman said on Friday. Bush, 90, was taken by ambulance to Houston Methodist Hospital on Tuesday night and admitted for observation after experiencing breathing difficulties earlier that evening, according to his spokesman, Jim McGrath.
