George HW Bush is in the hospital, but there's no need to panic, his chief of staff tells the Houston Chronicle. The former president has had a serious cough for the past few weeks, and was admitted to a Houston hospital last Friday with bronchitis. The 88-year-old had previously been in and out of the hospital for treatment, a source tells NBC News, and was admitted once again due to his age and out of "an abundance of caution." The situation is not life-threatening, and his chief of staff expects him to be discharged this weekend. "We have kept this quiet out of respect for him," she noted.
