She's since retracted the tweet and described it as "indefensible", with many stars in Roseanne criticising her over the comments.
Barr said she was considering fighting back after her show was cancelled.
Barr went on to suggest that Soros meant to "overthrow [the] us constitutional republic by buying/backing candidates 4 local district attorney races who will ignore USA law & favor "feelings" instead-and call everyone who is alarmed by that 'racist.'" When a correspondent made a reference to Valerie Jarrett helping to "hide a lot" during the Obama administration, Barr chimed in with her fateful comment, which she subsequently blamed on the sleeping drug Ambien.More news: Crypto-rehab center launches in Scotland
"Gee, he never called President Donald J. Trump to apologise for the frightful statements made and said about me on ABC. I will examine all of my options carefully and get back to U". "LIBERAL BIAS!" said Students for Trump Chairman Ryan Fournier.
Although President Trump didn't explicitly come to Barr's defense, he did imply ABC was guilty of hypocrisy. No one is defending what [Roseanne] said, ' she said.
On Thursday, he targeted the executive again on Twitter: "Iger, where is my call of apology?"
"He said he had zero tolerance for that sort of racist, bigoted comment and he wanted me to know before he made it public that he was canceling his show and so I appreciate that they did that so swiftly".More news: Trump to pardon Dinesh D’Souza
Iger himself stepped down from one of the panels earlier in the year, following the president's decision to exit the Paris accord on climate change. Iger told Vogue magazine last month that he had considered running for president but decided against it to focus on business.

Barr blamed her late-night message on the sleep aid Ambien. In response to tweets calling out Gilbert and Emma Kenney, who plays Barr's granddaughter, Barr wrote, "i feel bad for @POTUS-he goes thru this every single day". "I made a mistake I wish I hadn't but...don't defend it please". That led the drug maker Sanofi to say on social media that "racism is not a known side effect" of their product. Barr deleted the tweet and later apologized to Jarrett and "all Americans".
Daily Wire contributor Michael Knowles said while Barr's tweet was in poor taste, "the popular furor to fire her is mostly performed and motivated by the Left's hysterical contempt for anyone even vaguely supportive of President Trump". She apologized to those who had lost their jobs because of her action, but also condemned cast members who threw her under the bus, in her words.More news: Trump plans to hit Canada with steel, aluminum tariffs today
"Or [that Barr] had made some agreement, at the beginning of the show, to maybe stay off Twitter", he said.
