Roseanne Barr is lobbying to be “uncanceled” following her fallout with Hollywood in 2018 after racist tweets about President Obama’s advisor Valerie Jarrett. Barr, the star of 1990’s sitcom “Roseanne,” had the reboot of the show yanked off the air in the wake of the tweets. Now in a new documentary, she says she was not given an opportunity to apologize for her actions, which she says happened under the influence of the prescription drug Ambien.
