George HW Bush spent Christmas in the Houston hospital where he was taken after experiencing shortness of breath Tuesday night, but he had a "terrific day" and is "in great spirits," a spokesman says. The 90-year-old was visited by wife Barbara and other family members, and the spokesman says Bush "asked that his sincere wishes for a very Merry Christmas be extended to one and all," NBC reports. The spokesman says Bush's prognosis is positive, and the former president's chief of staff says that unlike two years ago, when Bush spent two months in hospital with bronchitis and other health problems, this is just a "hiccup" and he should be home within a few days, reports CNN.
