ABC cancels popular sitcom “Roseanne” following racist tweet by main protagonist Roseanne Barr where she called former Obama advisor an ape.

ABC canceled its hit sitcom “Roseanne” on Tuesday after the show’s biggest star, Roseanne Barr, went on a racist Twitter rant.

ABC took the decision following what it called “abhorrent” comments from the show’s star, Roseanne Barr, who had compared former Obama advisor Valerie Jarrett to an ape.

In a since-deleted tweet, Barr said of Jarrett: “muslim brotherhood & planet of the apes had a baby=vj.”

Critics immediately slammed Barr’s remark as racist. Likening black people to apes is an attack commonly used by racists. The Muslim Brotherhood, meanwhile, is an Islamist political group. Barr had apologised for her comments earlier in the day and said she would be refraining from using her Twitter account, which was still live at the time of publication.

Just an hour later, Barr’s talent agency ICM Partners dropped her as a client, the firm confirmed to CNBC.

“Roseanne’s Twitter statement is abhorrent, repugnant and inconsistent with our values, and we have decided to cancel her show,” ABC Entertainment president Channing Dungey said in a statement. Disney CEO Bob Iger added on Twitter that “there was only one thing to do here, and that was the right thing.”

Barr also targeted Chelsea Clinton by calling her “Chelsea Soros Clinton.” She later replied in the comments that Clinton is “married to Soros nephew.” Soros is a billionaire liberal benefactor who has been the villain in many right-wing conspiracy theories over the years.

The decision has ripple effects from the cancellation. At least 200 jobs will be affected, according to industry sources.
