ABC announced Tuesday that it has canceled the Roseanne reboot after Roseanne Barr made a racist and Islamophobic "joke" on Twitter. "Roseanne's Twitter statement is abhorrent, repugnant, and inconsistent with our values, and we have decided to cancel her show," said ABC in a statement. Barr had apologized for her tweet, saying it was "in bad taste," and claimed she was "leaving Twitter" following the resulting backlash.
