It'll be a packed stage for 12 candidates in Westerville, Ohio for the fourth democratic presidential debate. But one person threatens to take the spotlight -- and he won't even be there. Hunter Biden gave his first interview since he and his father became the targets of attacks from the President and his allies about his foreign business deals. NBC’s Mike Memoli, Former Director of Strategic Communications for Hillary Clinton's 2016 campaign Adrienne Elrod, and National Political Director for the Indivisible Project Maria Urbina join Craig Melvin to discuss.
