Former President George H.W. Bush was hospitalized in Maine on Sunday, days after greeting well-wishers upon his arrival in Kennebunkport.
"President @GeorgeHWBush was taken to Southern Maine Health Care (@SMHCHealth) today after experiencing low blood pressure and fatigue," Bush spokesman Jim McGrath wrote on Twitter.
The 41st president was hospitalized in Texas shortly after the death of his wife, Barbara Bush, in April.
Bush will remain at Southern Maine Health Care for further monitoring for a few days, McGrath added.
