His wife, former First Lady
On Christmas, his office said, the 41st president received visits from his wife and from son and daughter-in-law Neil and Maria Bush.
It wasn't the first time Bush had been hospitalized over Christmas. In November 2012, he went to Houston Methodist with a persistent cough. He developed a fever and stayed nearly two months.
Last year, Barbara Bush was admitted to the same hospital on New Year's Eve with signs of pneumonia. She was released after six days of treatment.
Bush -- the father of former President George W. Bush and former Florida Gov.
-- made headlines in June when he celebrated his 90th birthday by skydiving.
