President Obama's farewell address was full of highlights, including his touching message to Joe Biden.
"To Joe Biden, the scrappy kid from Scranton who became Delaware's favourite son. You were the first decision I made as a nominee, and it was the best," said Obama. "Not just because you have been a great vice president, but because in the bargain, I gained a brother. And we love you and Jill like family, and your friendship has been one of the great joys of our lives."
