Allegations of misconduct by Charlie Rose at CBS were widespread and three managers at the network were warned about his conduct toward women, according to an investigation by The Washington Post.

“An additional 27 women — 14 CBS News employees and 13 who worked with him elsewhere — said Rose sexually harassed them,” the paper reports. “Concerns about Rose’s behavior were flagged to managers at the network as early as 1986 and as recently as April 2017, when Rose was co-anchor of ‘CBS This Morning,’ according to multiple people with firsthand knowledge of the conversations.”

The paper says Rose provided a one-sentence email in response to getting word about the new allegations, writing: “Your story is unfair and inaccurate.”

“The new allegations follow an earlier Post report on Rose’s behavior at his namesake PBS program, in which eight women accused the TV star of making lewd phone calls, walking around naked in their presence, or groping their breasts, buttocks or genital areas,” the story reports. “Rose issued an apology. His PBS show was canceled and he was fired from CBS News.”

The Post reportedly conducted its investigation over a five-month period, speaking with 107 current and former CBS News employees, among others.

“The new allegations against Rose date to 1976, when, according to a former research assistant, he exposed his penis and touched her breasts in the NBC News Washington bureau where they worked,” The Post reports.

The former research assistant, Joana Matthias, is quoted saying: “This other personality would come through, and the groping would happen.”

The report adds: “At CBS News, where in addition to the morning show Rose worked as a contributing correspondent for ’60 Minutes,’ some women who said they were harassed said they feared reporting the violations to executives, whom they viewed as prioritizing the careers of male stars.”
