Former President George H.W. Bush and his wife, former First Lady Barbara Bush, have both been hospitalized. Bush's spokesman Jim McGrath "[The cause for the former President's hospitalization was] an acute respiratory problem stemming from pneumonia. Doctors performed a procedure to protect and clear his airway that required sedation." He said Bush is responding well to treatments. Barbara Bush also was admitted to the hospital Wednesday morning as a precaution after "experiencing fatigue and coughing," McGrath said in the statement.
