Jimmy and Rosalynn Carter will not be at Barbara Bush’s funeral Saturday.

“President and Mrs. Carter regret that they are unable to attend,” the Carter Center in Atlanta said in a statement Thursday morning. “President Carter will be on a private trip overseas, and although she is recovering, Mrs. Carter is not yet able to travel following her recent intestinal surgery.”

Rosalynn Carter, 90, had surgery on Feb. 18 to remove "troubling scar tissue" from a portion of her small intestine. Three weeks later, the 93-year-old former president happily informed the Sunday school class he was teaching at Maranatha Baptist Church in Plains that his wife had just phoned him to say that she was finally on her way home from Atlanta, where she'd been recovering following the surgery at Emory University Hospital.
