Jackie Mayo, public information officer for Cleveland Hopkins International Airport, said the 39th president was transferred to Metro Health Hospital at around 11:30 a.m. ET after paramedics met Carter's plane upon its arrival.
"While on a flight to Cleveland, former U.S. President Jimmy Carter developed an upset stomach, and, upon arrival, was taken to Metro Health Hospital for observation," said a statement from Carter Center spokeswoman Deanna Congileo. "He is resting comfortably and is expected to resume his book tour this week."
Last week, Carter, 85, appeared on the Today show, promoting his latest book, his 23rd, White House Diary. He looked to be in good health. Local Midwestern TV stations report that he was due for a book singing in Cleveland Tuesday afternoon.
In 2002, Carter was the recipient of the Nobel Peace Prize for his efforts "to find peaceful solutions to international conflicts, to advance democracy and human rights, and to promote economic and social development," said the prize committee.
