For nearly seven minutes, the Outnumbered co-hosts unleashed angry comments about the president for doling out advice to the incoming president.

Biden’s comment about Trump learning “decency” from Carter was in response to a question from a reporter who asked what the president-elect should learn from Carter, who died on Sunday at 100.

“Decency. Decency. Decency,” Biden began. “Everybody deserves a shot, everybody. Can you imagine Jimmy Carter walking by someone who needed something and just keeping (sic) walking? Can you imagine Jimmy Carter referring to someone by the way they look or talk? I can’t.”

Was Biden wrong? If so, what should President Trump learn from President Carter?
