WASHINGTON - Donald Trump may be unhappy again with Georgia Gov. Brian Kemp - the governor of Georgia honored former President Jimmy Carter for his 100th birthday.

"I have declared today 'Jimmy Carter Day' in the State of Georgia to recognize his legacy as our 76th Governor and 39th President," Kemp said in a statement posted on the X social media site. "Marty, the girls, and I send him best wishes as he and his family celebrate this milestone."

Trump, who has feuded with Kemp over the conduct of the 2020 election in Georgia, has attacked Carter throughout the election year, comparing his presidency to that of his former opponent, President Joe Biden.

The Carter family has expressed similarly dim views of Trump.

The Carter Center spent Tuesday posting a series of videos from people praising the 39th president, including successors Biden, Barack Obama, George W. Bush, and Bill Clinton - but nothing from Trump.

The state proclamation declaring "Jimmy Carter Day" said the former president "has remained a person of strong conviction and a dedicated believer in community service."

It added: "Of his many achievements, he is perhaps best known as a loving husband, caring humanitarian, and a valued Sunday School teacher."

Carter, who is in hospice care, spent the big day at his home in Plains, Ga.

CBS News took video of family and friends gathered in Carter's back yard. At one point, the nation's oldest-ever president was wheeled out to watch a military flyover.

Jason Carter, the former president's grandson, has told reporters that he wanted to keep living for one reason: To vote for Vice President Kamala Harris over Trump.
