KENNEBUNKPORT — Former President George H.W. Bush remained hospitalized Monday, forcing him to miss a local Memorial Day parade that he traditionally attends. The 93-year-old was taken to Southern Maine Health Care in Biddeford on Sunday after he experienced low blood pressure and fatigue. James McGrath, the president’s longtime spokesman, said Sunday that the president was “awake, alert and not in any discomfort,” but would likely stay at the hospital for a couple of days for observation. There was no change in his status late Monday, McGrath said. Earlier in the day, the president sent a message from his official Twitter account about missing the parade. “Very much regret missing the Memorial Day parade today in Kennebunkport, and am forever grateful not only to those patriots who made the ultimate sacrifice for our Nation – but also the Gold Star families whose heritage is imbued with their honor and heroism,” he wrote. Residents who attended the parade in Kennebunkport, down the road from Bush’s summer home at Walker’s Point, expressed concern for the nation’s 41st president. The event’s grand marshal, Tom Willey, mentioned the president in his remarks, wishing him a speedy recovery. “He’s such a figure at our parades.
