“Morning Joe” host Joe Scarborough is getting the pariah treatment from some of his MSNBC colleagues after he challenged the martyrization of Michael Brown, an 18-year-old African-American who was shot to death in August during a confrontation with white police officer Darren Wilson.

“It’s been fun, haha. If any booker calls me again, I’m down, but [don’t] ask me to ever do @JoeMSNBC. I have a conscience,” MSNBC regular and University of Pennsylvania professor Anthea Butler tweeted Wednesday, referring to the show “Morning Joe.”
