Five current and former presidents have come together for Jimmy Carter’s funeral.

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?

Jimmy Carter, the late U.S. president who served only one term in office and was widely admired for his humanitarian work after leaving the White House, was remembered during his state funeral on Thursday as a man who put honesty and kindness above partisan politics.
