The swift move from the network, the powerful statement from ABC president Channing Dungey and Barr's subsequent tweets make this one of the most infamous cancellations of a show in television history. She has since said that she took sleeping tablets before sending the tweet and that they were the reason for her freakish behaviour. "I just wish ABC had not thrown two of the greatest actors in the world out with me-Laurie and John", she posted.
The president was referring to ABC News reporter Brian Ross, who erroneously reported late past year that Trump had asked Michael Flynn to make contact with the Russians during the 2016 presidential campaign.
Trump wrote that Iger never called him to apologize for "the frightful statements" that have been said about him on ABC.
Ms Jarrett revealed that Mr Bob Iger, head of ABC parent company Disney, had called to tell her about the ditching of the show.
Mr Trump targeted Robert Iger on Twitter, saying: "Iger, where is my call of apology?"
The president, who took credit for the successful reboot and even called Barr to congratulate her, did not mention her firing at his rally in Nashville Tuesday night. The assertion that she has a connection to the Muslim Brotherhood, which she does not, also sparked intense anger on social media and calls to boycott or cancel the show. While asking not to be defended, she retweeted comments from supporters that attacked ABC and complained that conservatives are treated more harshly than liberals for their behavior.
Opinion writer Roxane Gay wrote in The New York Times Wednesday that ABC did the right in canceling "Roseanne".

"Our goal was to promote constructive discussion about the issues that divide us", said Tom Werner.
Gilbert said the remarks are "abhorrent and do not reflect the beliefs of our cast and crew or anyone associated with our show", adding that she is disappointed in her longtime friend and colleague. "More Networks and "papers" should do the same with their Fake News!"
Barr has previously apologised to Ms Jarrett, writing: "I want to apologize to you. It was only when Ms. Barr became an immediate liability that everyone involved finally looked at her racism and dealt with it directly".
In 2016, Barr went on a Twitter rant about Hillary Clinton.
It's unclear what statements Trump was referring to.
Three weeks earlier, "Roseanne" was the toast of ABC's annual presentation of its programming plans to advertisers. The firm estimates that the 13 episodes that had been ordered for next season would have brought in as much as $60 million, with more through repeat episodes. "I don't know anything about it", Goodman said when asked what his response was to the fallout.
