'Is he just that sick?' Ex-senator tries to figure out Trump's thought process at NABJ Q&A

Former U.S. Sen. Claire McCaskill struggled Wednesday to figure out why former President Donald Trump went to the National Association of Black Journalists, and in doing so, set his campaign aflame.

Speaking to MSNBC's Nicolle Wallace, McCaskill, a Missouri Democrat, questioned, "What did he think he was going to get?"

Trump kicked off the session by attacking it, refusing to answer questions, attacking the moderators, and questioning the legitimacy of Kamala Harris' race and identity.
