Jimmy Carter celebrates his 100th birthday, making history as the first former U.S. president to reach this remarkable milestone. Fellow presidents Joe Biden and Barack Obama extended their warm wishes, recognizing Carter as "a moral force for our nation and world." Biden led the tributes on Tuesday, honoring Carter's significant contributions throughout his life. Despite entering hospice care at his home in Plains, Georgia, 19 months ago, Carter remains engaged and has expressed his eagerness to vote for Kamala Harris, a fellow Democrat, in the upcoming presidential election. His grandson, Jason Carter, shared this sentiment, highlighting the former president's continued interest in participating in the democratic process.
