The tweet implied senior Obama adviser Valerie Jarrett was the offspring of the Muslim Brotherhood and an ape. Beyond her racially offensive tweet being "abhorrent" to the company's values, ABC executives had to realize that because there little chance of controlling the star of their biggest show, they had reason for knots in their stomachs, dreading more unwelcome surprises.
She also repeated her claim that she was under the influence of alcohol and sedatives at the time she posted the tweet. On Wednesday's broadcast of "The View", she said she wouldn't be watching Barr's sit-down with Hannity. "That's what was in my head", said Barr.
Addressing Jarrett directly, the comic said she "never meant" to cause hurt. When asked if she's ever been hospitalized for mental-health issues, she told Hannity, "Honey, that's like going to the beach for me". And I never meant that and for that I apologize. "It cost me everything, my life's work, and I've paid the price for it".
"I want to apologize to [the viewers], too", Barr said.
At one point, Hannity asked what Barr would say to Jarrett if she could talk to her directly. "She needs a new haircut".
"I don't suffer from it any more", Barr corrected.
Barr's tweet sparked outrage on social media in May and led ABC to cancel the reboot of her self-titled show about a working-class American family. Barr discussed everything from her mental issues to a desire to take the opposite side to whatever belief was held by people now in power.
Putin says US-Russia summit was successful
A White House spokeswoman, Lindsay Walters, wanted to make clear that the president "respects the independence of the Fed". So, we will see what comes of this, but I think the Russians are going to see if the USA wants this more than they do.
Jarrett, for her part, has largely sidestepped the controversy.
"We could turn this into a really great, teachable moment", Barr told Hannity.
"And then everybody started saying I was a racist", Barr continued, "which is like the worst thing you could call a Jewish person, especially one who like me, grew up with Holocaust survivors".
ABC has since confirmed it will broadcast a spin-off called "The Connors" - featuring cast members including John Goodman and Laurie Metcalf - after Barr relinquished any creative or financial involvement.
Roseanne Barr has just given a masterclass on how not to apologize for a massive public flameout.
