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.)

Trump is obviously no fan of Biden, but Obama and his veep also have a famously complex relationship, only made more so after Obama helped nudge Biden to quit the presidential race last summer. Surely Obama feels some frustration that Biden fumbled a possibly winnable race; maybe he couldn’t help spill to his sworn enemy?

“Former First Lady Michelle Obama is not in attendance at President Carter’s National Funeral Service," according to the statement from spokesperson Crystal Carson. "Mrs. Obama sends her thoughts and prayers to the Carter family, and everyone who loved and learned from the remarkable former President.”
