Updated at 3:50 p.m. ETAfter Roseanne Barr posted a series of incendiary tweets, ABC canceled the reboot of her eponymous sitcom."Roseanne's Twitter statement is abhorrent, repugnant and inconsistent with our values, and we have decided to cancel her show," said ABC Entertainment President Channing Dungey in a one-sentence statement Tuesday. Robert Iger, chairman and CEO of The Walt Disney Co., which owns ABC, shared Dungey's statement and added, "There was only one thing to do here, and that was the right thing."In a now deleted tweet, Barr wrote of former White House adviser Valerie Jarrett, if "muslim brotherhood & planet of the apes had a baby=vj."Although Barr has long had a controversial Twitter presence, that comment crossed a line."I apologize to Valerie Jarrett and to all Americans," Barr tweeted Tuesday morning. "I am truly sorry for making a bad joke about her politics and her looks. I should have known better. Forgive me--my joke was in bad taste."Comedian Wanda Sykes, who had been a consulting producer on the show, tweeted that she would not return to the program.The comment about Jarrett was one in a series of controversial tweets by Barr this week.On Monday, one of her tweets said only "Chelsea Soros Clinton".Chelsea Clinton replied, "Good morning Roseanne - my given middle name is Victoria. I imagine George Soros's nephews are lovely people. I'm just not married to one. I am grateful for the important work @OpenSociety does in the world. Have a great day!"To which Barr replied: "Sorry to have tweeted incorrect info about you!I Please forgive me! By the way, George Soros is a nazi who turned in his fellow Jews 2 be murdered in German concentration camps & stole their wealth-were you aware of that? But, we all make mistakes, right Chelsea?"Some conspiracy theorists claim that Soros, the billionaire and left-leaning donor, was a Nazi collaborator or a member of the SS – a rumor that has been debunked.Deadline Hollywood reports that Barr has also been dropped by her agency, ICM Partners. "We are all greatly distressed by the disgraceful and unacceptable tweet from Roseanne Barr this morning," said a memo to company employees, according to the entertainment site. "What she wrote is antithetical to our core values, both as individuals and as an agency. Consequently, we have notified her that we will not represent her. Effective immediately, Roseanne Barr is no longer a client."She signed with the agency in August, Variety reports.Roseanne originally aired from 1988 until 1997, telling the story of the working-class Conner family in Illinois. It was relaunched by ABC in March with much of its original cast, including John Goodman, Laurie Metcalf and Sara Gilbert, in addition to Barr herself.The show garnered considerable media attention, largely because of storylines about the Roseanne character being a Trump voter. As NPR's Eric Deggans noted, the reboot seemed to contrast with the values of the original show:
