HOUSTON, Texas (AP): A spokesman for former President George H.W. Bush says Bush has been admitted to the intensive care unit at Houston’s Methodist Hospital to address a respiratory problem from pneumonia.

Spokesman Jim McGrath says Bush’s wife, Barbara Bush, also has been hospitalized as a precaution after experiencing fatigue and coughing.

McGrath says the 92-year-old former president was placed under sedation for a procedure to protect and clear his airway. He is stable and resting comfortably. He has been in the hospital since Saturday.

Barbara Bush is 91. The couple marked their 72nd wedding anniversary on Jan. 6.

McGrath says in an email to The Associated Press that Bush has responded well to treatments and that doctors are pleased with his progress.

Bush served as U.S. president from 1989 to 1993. He has a form of Parkinson’s disease and uses a motorized scooter or a wheelchair for mobility.
