Bush.

George H.W. Bush, the nation's 41st president, will not attend. He wrote in a letter to the president-elect that he was not well enough to make an in-person appearance.

"My doctor says if I sit outside in January, it likely will put me six feet under. Same for Barbara. So I guess we're stuck in Texas," Bush wrote earlier this month.

Bush is currently hospitalized after undergoing a procedure to clear his airways on Wednesday.

Carter endorsed Hillary Clinton during the 2016 campaign, though he noted that neither her nor Trump were “quite unpopular.”
