Former Vice President Joe Biden speaks at the University of Utah Thursday Dec. 13, 2018, in Salt Lake City. Biden says he initially refused to run with then-presidential candidate Barack Obama a decade ago, but his family ultimately convinced him he had to support an African-American candidate with a real chance of winning. Biden was greeted with a standing ovation when he spoke amid speculation about whether he'll launch his own campaign for president. He did not directly address the possibility of another run in the speech that marks his final public event for 2018. (AP Photo/Rick Bowmer)
