On the 18 May 2016 edition of CNN Newsroom, Carol Costello hounded Bernie Sanders surrogate Charles Chamberlain over the chaos at Nevada's Democratic state convention between the supporters of Hillary Clinton and Bernie Sanders. Costello accused Sanders's director for delegates of "egging things on in Nevada." She later wondered, "How are these supporters for Bernie Sanders different from the supporters of Donald Trump...they also think that the system is rigged, and they're accused of violence." Meanwhile, the anchor tossed softball questions at a Hillary Clinton supporter.
