Roseanne Barr is still madly tweeting (after quitting Twitter) due to her racially-charged tweet against Obama advisor Valerie Jarrett, which led to Roseanne?s swift cancellation by ABC, which was seen as a sign of progress by many. She blamed the A-A-Ambien and has continued to argue that her tweet was ?insensitive, not racist,? and she claims to have thought Jarrett is white or maybe Saudi, so she can?t be racist.
