MINNEAPOLIS (AP) — Former Vice President Walter Mondale is hospitalized with the flu.

Mondale was supposed to introduce former President Jimmy Carter on Friday at the annual Nobel Peace Prize Forum.

Instead, Carter told the crowd that his former vice president was at the Mayo Clinic in Rochester.

The St. Paul Pioneer Press reports that Carter told the audience that he spoke with the 87-year-old Mondale and "he told me to tell everyone that he is doing well."

Messages left Friday with the Mayo Clinic and with Mondale's son Ted were not immediately returned to The Associated Press.

In addition to serving as vice president, Mondale was a U.S. senator and ambassador to Japan.
