Former President George H.W. Bush was taken to the hospital Sunday in Maine after experiencing low blood pressure and fatigue.
Jim McGrath, Bush's spokesperson, says he will likely remain in there for the next several days for observation.
Bush is awake and alert. He is not in any pain, according to McGrath.
Bush arrived in Kennebunkport, Maine about a week ago to spend his summer vacation.
He was released from the hospital earlier this month after he was hospitalized with an infection April 22, a day after the funeral for his wife, former first lady Barbara Bush.
