The head of ABC Entertainment said Tuesday the network has canceled the TV show “Roseanne,” after its main character, Roseanne Barr, sent racist tweets attacking a former adviser of President Barack Obama. Roseanne early Tuesday tweeted: “Muslim brotherhood & planet of the apes had a baby=vj,’referring to Valerie Jarrett. The tweet was in response to a Twitter thread accusing Jarrett, who is African American, of helping to cover up CIA spying. Barr apologized for the tweet, before saying she was leaving Twitter. “Roseanne’s Twitter statement is abhorrent, repugnant and inconsistent with our values, and we have decided to cancel her show,” Channing Dungey, president of ABC Entertainment, said in a statement. The rebooted show, which drew more than 18 million viewers to its March premiere, had been a big hit for ABC. Disney shares were last down 2.5% and have fallen 7% in the year to date, while the S&P 500 has gained 0.4%.
