And after blaming the sleep medication for the Twitter rant, Barr also turned to a surprising target - her "Roseanne" team.
Mr. Rasmussen, who was a supervising producer for one season on the old show before being fired, said there was a sense of goal this time that the show could speak to a segment of the country that was often overlooked in prime-time TV.
Roseanne Barr has always been a controversial figure, and certainly, in the years since her ABC sitcom initially went off the air, her views have become increasingly weird and extreme. "If I was Roger, I wouldn't have liked it but I enjoyed it".

"I feel devastated, not for the end of the Roseanne show, but for all those who poured their hearts and souls into our jobs, and the audience welcomes us into their homes".More news: USGS: Please don't roast marshmallows over Hawaii volcano

Trump has cited the programme's popularity as evidence that his supporters, who include Barr, want shows that speak to their concerns.
Barr also tweeted: "no, i didnt i blamed myself. stop lying".
Before and after that post, Barr retweeted fans who portrayed her as a victim of a liberal media double standard.
In response to Sara Gilbert's tweet - in which she labelled Roseanne's comments "abhorrent" - she simply wrote: 'Wow!
