Bush is the oldest-living former president and vice president. He is also the last living former president who is a veteran of World War II.
“President Obama and the first lady send their good wishes to the former president and the entire Bush family during this holiday season,” Schultz said.
Bush, who can no longer use his legs, most recently appeared seated in a wheelchair at an event in November at Texas A&M University with his son, former president George W. Bush.
In June, the elder Bush celebrated his 90th birthday by making a tandem parachute jump near his summer home in Maine.
