President Joe Biden and former President Jimmy Carter have a long history of friendship and mutual respect, with Carter endorsing Biden in the 2020 election and presenting him with the Presidential Medal of Freedom in 2002. At a fundraiser in Rancho Santa Fe, California, Biden announced that Carter had asked him to deliver his eulogy when he passes away. Carter, 91, is currently the longest-living president in United States history and has been in hospice care since 2015.
