Barr, who had apologised for her comments, tried to further fix the damage on Wednesday, tweeting: "I'm not a racist, I never was & I never will be".
U.S. President Donald Trump waded into the discussion on Wednesday morning, asking why Disney chief executive Bob Iger didn't ever call him. "I'm so sick over this - they will never have better character actors on their network", Barr wrote.

In addition, Roseanne Barr's firing from the network left stars of other ABC television shows extremely happy. "And I think that we have a lot bigger things going on in the country right now, certainly, that the president is spending his time on".
She also wrote: "Give Ireland back to the British too". "I don't know anything about it", Goodman said when asked what his response was to the fallout.
