On Thursday, all living presidents and spouses attended Jimmy Carter's funeral, except Michelle Obama. Here's why.

George W. Bush gave fellow former president Barack Obama a friendly belly tap at the Jan. 9 funeral of Jimmy Carter, and the internet was obsessed with the viral moment. In the first test of how receptive the court may be to Trump, 4 of the court's 6 conservative members said they would have granted his emergency request.

The former president and once-again-future president, who are historically something less than besties, chatted it up before the service began. (Michelle Obama was not in attendance.)
