The comedian, who said she "became the PC police" (https://www.hollywoodreporter.com/features/roseanne-returns-is-tv-ready-a-trump-loving-comic-nothing-left-prove-1086651) on Roseanne while helping shepherd the revival, "is going to be too busy" for next season, according to her fellow co-showrunner Bruce Helford. He adds that "Whitney is always a member of the family of the show but she's got so much going on. I don't know how she had time to work on the show in the first place. I don't think she'll be able to join us in the capacity she was joining us in this first season." Cummings, who co-created 2 Broke Girls, was working with Roseanne executive producer Tom Werner of Carsey-Werner when he proposed that she help lead the revival. Cummings said when Werner “called me and he said, ‘We’re doing this. Do you want to be a part of it?’ … I canceled everything I had going on and made myself available (http://www.philly.com/philly/entertainment/television/roseanne-whitney-cummings-abc-penn-20180326.html), if anything just to go in and learn from these writers.” Helford also said Roseanne will bring in a group of new writers for Season 2: "We have a lot of new voices, younger voices, which I think is important on the show. I'll be showrunning next season. We run a democratic room, almost nobody has a stronger voice than anybody else; everybody's input is there. I'm excited because there are a lot of new voices and because I believe we've got the best of the voices who have been part of it continuing." UPDATE: Cummings confirms her exit on Twitter (https://twitter.com/WhitneyCummings/status/997538572768108545): "Due to work commitments and my tour schedule, I'm gonna have to watch the Conner's from the sidelines next season."

Hmmm. Sounds like next season will be boring. But I'll reserve judgment until after I watch next season's episodes.

Whitney Cummings defends Roseanne's controversial joke about Black-ish and Fresh Off the Boat (http://www.vulture.com/2018/06/whitney-cummings-defends-roseanne-joke-about-diverse-tv.html)
The former Roseanne co-showrunner said on The Hollywood Reporter's comedy showrunner's roundtable (https://www.hollywoodreporter.com/features/comedy-writers-fate-humor-at-comedy-showrunners-roundtable-1118121) that it would be disingenuous to mask the real views of the Conners family. Cummings adds: "There are times where I’m like, ‘This is offensive, but this is what they would say when no one is watching and when they don’t have a bunch of lib-tard people controlling what they say.’ So, I found a lot of times my job was just to go, ‘If you feel that that’s what this person would say behind closed doors, then let’s go with it.’”

Whitney Cummings: "It's a bad move" if Roseanne Barr benefits from a Roseanne spinoff without her (http://www.tmz.com/2018/06/11/whitney-cummings-pissed-angry-roseanne-cancellation-reboot/)
Cummings tells TMZ she "quit months ago," even though her departure as co-showrunner (http://tvline.com/2018/05/18/roseanne-whitney-cummings-leaving-showrunner-season-11-abc/) was announced 11 days before ABC canceled Roseanne following Roseanne Barr's racist tweet. Cummings declined to address TMZ's question of whether she'd seen the writing on the wall. "I have too many grey hairs in my head from this whole experience," she said later. Asked if Roseanne Conner should be killed off for the potential spinoff, Cummings said: "I can't think of any funny ways to kill Roseanne, but I don't want to think about it. Killing her would mean I'd have to think about her and I don't want to do that right now. I'm too pissed off."
