Morgan had quit her job on ITV’s “Good Morning Britain” following accusations of racism over the negative comments she made after Prince Harry and Meghan Markle’s interview with Oprah Winfrey.
Osbourne demanded that Underwood bring cases where Morgan had been a racist; he was visibly upset during the exchange; and warned Underwood not to cry, saying that if anyone cried it should be Osbourne.
Osbourne later tweeted an apology, saying she “panicked,” “felt shocked,” and then “got defensive” during the conversation.
After the episode, CBS announced that an internal review would take place and the show was discontinued in production.
Shortly thereafter, an article appeared in which former “Talk” co-host Leah Remini and several anonymous sources accused Osbourne of using racist and homophobic language about his colleagues.
CNN did not independently verify the claims, but a Remini spokesperson confirmed the veracity of their statements and declined to comment further.
Underwood said he had “heard things” before starting work on the show, but said, “You have all kinds of personalities in this business.”
On March 26, CBS announced that Osbourne would be leaving the show.
Underwood said he has not spoken to Osbourne since their argument.
An Osbourne spokesperson issued a “no comment” when contacted by CNN.
“The Talk” will return without Osbourne on March 12.
