Washington (CNN) Former President George H.W. Bush was taken to a hospital in Maine on Sunday after experiencing low blood pressure and fatigue.

"I guess he partied too hard with the American Legion yesterday," wrote Jean Becker, Bush's chief of staff, in an email to the former president's family and friends. "Darn it.

"President George H.W. Bush was taken to Southern Maine Health Care today after experiencing low blood pressure and fatigue. He likely will remain there for a few days for observation. The former president is awake and alert, and not in any discomfort."

Bush was previously admitted to a Houston hospital last month after contracting an infection that spread to his blood the day after a funeral was held for his wife, Barbara Bush. He was discharged from the hospital on May 4.

Bush spends his summers in Maine. He arrived in the state on May 20, about a month after his wife's death.

Delighted to join the veterans, including my dear friend Gen. Brent Scowcroft, at the @AmericanLegion Post 159 monthly pancake breakfast in Kennebunkport today. This weekend we remember, and thank, all who have given their lives for our great country. pic.twitter.com/VQgfPmt5rw — George Bush (@GeorgeHWBush) May 26, 2018
