ABC Entertainment President Channing Dungey said the comment "is abhorrent, repugnant and inconsistent with our values".
In March, Barr told ABC's Good Morning America that US President Donald Trump had called her to congratulate the ratings success her revived sitcom had experienced.
She deleted the post and apologised but could not contain the backlash. Clinton herself corrected Barr online, and Donald Trump Jr. retweeted two of Barr's statements about Soros, although not the remark about Jarrett.
The Laff comedy channel is removing all "Roseanne" episodes from its schedule following Roseanne Barr's racist tweet. The Disney-owned television network released a statement today explaining their decision.
The "Roseanne" reboot was ABC's biggest hit of the 2017-2018 season, drawing an average 18.7 million viewers, second only to CBS sitcom "The Big Bang Theory".
She also apologized personally to Jarrett.
ICM dropped Barr within hours of the cancellation, saying in a statement that the agency was "greatly distressed by the disgraceful and unacceptable" tweet.
Hysteria Aside, Losing Track of Immigrant Kids Nothing New
During those two months a total of about 8,400 unaccompanied minors were caught on the southwest border. It's more accurate to say the government lost track of them, as Bharara put it.
The company says it has ended its relationship with Barr "effective immediately".
Executive producer and co-star Sara Gilbert said that Barr's comments are "abhorrent and do not reflect the beliefs of our cast and crew or anyone associated with our show".
Roseanne, who had blamed Ambien in part for the tweet heard 'round the world, fired back Wednesday morning, replying to Gilbert's message with a tweet that said "Wow! unreal".
She then tweeted that she was quitting the social media platform, writing: "I apologize".
Others approving of the move included Georgia Congressman John Lewis.
The "Roseanne" revival this spring was an unexpected major hit for ABC.
The Muslim Brotherhood is an Islamist organisation and Planet of the Apes is a movie in which intelligent apes battle humans for control. "I'm exhausted of being attacked and belittled more than other comedians who have said worse", she tweeted. "I am truly sorry for making a bad joke about her politics and her looks", Barr said. Jarrett, an African-American, was born in Iran to American parents.
