Former President Jimmy Carter was transported by ambulance to a Cleveland hospital after falling ill during a flight, The Carter Center said Tuesday in a statement.
"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," according to a statement released by The Carter Center in Atlanta. "He is resting comfortably and is expected to resume his book tour this week."
Carter has since been released from the hospital, according to a message posted on his grandson's Facebook page that read, "he is fine," the Associated Press reported.
An ambulance met the Delta aircraft Carter had been traveling on when it landed just after 11:30 a.m. this morning at the Cleveland Hopkins International Airport, according to the airport's public information officer Jacqueline Mayo.
"Former President Jimmy Carter was taken by ambulance to MetroHealth Hospital when he landed," said Mayo.
Mayo was not sure whether Carter, 85, was taken off the plane on a stretcher.
MetroHealth Center has deferred all Carter inquiries to The Carter Center.
A volunteer at the Carter Center in Atlanta, Ga., told ABC News that the former president is not suffering from life-threatening injuries and had just fallen "air sick" on the flight to Cleveland, where he was scheduled to appear at a signing for his new book, "White House Diary."
"He threw up, he was air sick when he got off the plane," said Carter Center volunteer Bernice Moore. "He was not hospitalized."
