Carter in hospital for second night
Former US President Jimmy Carter is to spend a second night in hospital under observation after being taken ill with a stomach upset.
Carter's medical team continues to observe his progress, said Christina Karas, spokeswoman at MetroHealth Medical Center in Cleveland.
"President Carter is in very good spirits, appreciates all the good wishes being sent his way, and looks forward to getting back to his busy schedule," Karas said.
The 85-year-old became ill on a flight to Cleveland on Tuesday during a tour to promote his new book White House Diary.
Carter's publisher cancelled scheduled events in Washington today.
Carter's grandson, Georgia state Senator Jason Carter, said his grandfather was doing fine.
"He's definitely resting comfortably and expected to continue his book tour this week," Jason Carter said. "I haven't talked to him, but nobody in the family is concerned."
Carter, a former peanut farmer elected to the White House in 1976, has spent his recent years pursuing peace and human rights, efforts that won him the Nobel Peace Prize in 2002.
