After Duncan reported on the text, anchor Jeff Glor told her that Fager's message was "unacceptable" and that "the entire CBS News team" supports her.
Duncan showed a text message, apparently from Fager, which read, "If you repeat these false accusations without any of your own reporting to back them up you will be held responsible for harming me".
Fager has denied charges made by former CBS employees in the New Yorker magazine of personal misbehavior at parties and not disciplining people under him who had misconduct issues. A CBS News reporter working on a story about Fager revealed that he had sent her a text message urging her to "be careful".
60 Minutes executive editor Bill Owens will manage the show until Fager's replacement is found, Rhodes said, adding, "This action today is not directly related to the allegations surfaced in press reports, which continue to be investigated independently".
He said Mr Fager had "violated company policy", without elaborating on how.More news: Pope To Meet With U.S. Church Leaders Over Clergy Sex Abuse

The latest allegation against Fager comes from Sarah Johansen, a former CBS intern, who told Farrow that the "60 Minutes" executive producer groped her at a work party. "I don't care if 30 more women come forward and allege this kind of stuff", board member Arnold Kopelson is alleged to have said in a meeting shortly afterwards, "Les is our leader and it wouldn't change my opinion of him".
In the first New Yorker report, former colleagues also accused Mr Fager of inappropriate touching, and of protecting men accused of sexual misconduct. My language was harsh and, despite the fact that journalists receive harsh demands for fairness all the time, CBS did not like it.
"60 Minutes" is the most popular and powerful news broadcast on television, and Fager is only the second person to lead it during its 50 years of history. And Fager allowed a senior producer, Michael Radutzky, to engage in a pattern of abusive conduct in the workplace over a number of years - including an incident in which he allegedly twisted a female staffer's arm behind her back.
It was shortly after outlets began to pick up the news of Fager's exit that he released a statement of his own, in light of CBS News' refusing to comment on his specific violation. Rhodes was then brought in as news president, taking over full management of the news division when Fager went back to exclusively running "60 Minutes".
