Former President George H.W. Bush says he will not be attending President-elect Donald Trump's Jan. 20 inauguration due to poor health.
The 41st president wrote a letter to Trump from Houston Methodist Hospital in Texas apologizing for his absence, the New York Daily News reports.
While Bush is currently in stable condition, doctors worry attending the event would be too risky.
“My doctor says if I sit outside in January, it likely will put me six feet under," wrote Bush, 92, who was hospitalized on Jan. 14 alongside his wife. "Same for Barbara. So I guess we’re stuck in Texas.”
He ended the short note wishing Trump the "very best."
"But we will be with you and the country in spirit," added Bush. "I want you to know that I wish you the very best as you begin this incredible journey of leading our great country. If I can ever be of help, please let me know."
George H.W. Bush will be the only living president absent from Trump's inauguration, reports Politico. His son, former President George W. Bush, will be at the ceremony.
He will be joined by outgoing President Barack Obama as well as Presidents Bill Clinton and Jimmy Carter. Trump and the Bush family have a notoriously rocky relationship.
During his campaign, Trump mocked his Republican primary rival, former Florida Gov. Jeb Bush, describing him as “low energy." Jeb Bush is George H.W. Bush's son and George W. Bush's brother. Later in the campaign, the Bushes refused to attend Trump's Ohio nomination conference in summer 2016.
"I do not believe Donald Trump reflects the principles or inclusive legacy of the Republican Party," Jeb Bush wrote shortly before the convention in a Washington Post piece. "And I sincerely hope he doesn’t represent its future."
"They have given rise to the success of a candidate who continues to grotesquely manipulate the deeply felt anger of many Americans," Jeb Bush added. "Trump's abrasive, Know Nothing-like nativist rhetoric has blocked out sober discourse about how to tackle America's big challenges."
Despite their differences, the Bushes sent their congratulations to Trump when he won the election.
