Only one former president has indicated he will attend President-elect Donald Trump's inauguration next month.

Jimmy Carter recently announced to his Sunday school class in Georgia that he plans to attend the Jan. 20 event.

George W. Bush and Bill Clinton will make a decision in the coming weeks, according to Politico.

A spokesman for George H.W. Bush told Politico the 41st president won't attend inauguration because of his age. The former president is 92.

Neither of the two Bushes endorsed Trump during campaign after a brutal primary against Jeb Bush.

The Clinton camp has been divided over whether Bill Clinton should attend the inauguration.

A source close to former Democrat nominee Hillary Clinton's campaign told Politico that the former president is leaning toward skipping the event.

It wouldn't be the first time a former president didn't attend.

The Bushes skipped Obama's second inauguration in 2013 because of the elder Bush's health.

Gerald Ford skipped George W. Bush's second inauguration in 2005, when the former president was 91.
