While George H.W. Bush remains in the intensive care unit of a Houston hospital after experiencing "shortness of breath," the former president's wife, Barbara, has also been admitted for a separate health issue. The former first lady was taken to Houston Methodist Hospital on Wednesday morning "as a precaution after experiencing fatigue and coughing," spokesman Jim McGrath said in a new statement following an update on her husband's condition. Bush, who served as U.S. president from 1989 to 1993, has a form of Parkinson's disease and uses a motorized scooter or a wheelchair for mobility. His office announced earlier this month that George H.W. and Barbara would not attend Donald Trump's inauguration this week due to the former president's age and health.
