Several hours after conspiracy theorist and pro-Trump comedian Roseanne Barr tweeted a racist attack on former Obama adviser Valerie Jarrett, ABC announced its decision to cancel Barr’s TV show, Roseanne. The show has received an outpouring of support from conservatives since its March premiere, and, despite Barr’s documented history of extremism, President Donald Trump has reportedly praised her. During an appearance on Fox’s The Daily Briefing, Fox politics editor Chris Stirewalt argued that Trump should resist defending Roseanne after this latest scandal.
