CBS said Tuesday that it has fired Charlie Rose “effective immediately,” following an extensive Washington Post report that detailed alleged unwanted sexual advances toward women by the 75-year-old broadcaster.

His firing was announced by CBS News President David Rhodes, who wrote in a midday memo to the network’s staff that the action “followed the revelation yesterday of extremely disturbing and intolerable behavior said to have revolved around (Rose’s) PBS program.”

“Despite Charlie’s important journalistic contribution to our news division, there is absolutely nothing more important, in this or any organization, than ensuring a safe, professional workplace — a supportive environment where people feel they can do their best work. We need to be such a place.”

PBS also ended its partnership with Rose Tuesday. Rose has interviewed newsmakers in the media, entertainment, business and politics weeknights on PBS’ schedule since 1991. PBS had suspended his show late Monday.

Rose — best known for his award-winning interview program on PBS — had co-hosted “CBS This Morning” since the show’s launch in 2012 and was a contributing correspondent for the network’s Sunday night show, “60 Minutes.”

Eight women, who were either employees or aspired to work for Rose at the “Charlie Rose” show, told The Post that he made unwanted sexual advances to them between the late 1990s and 2011. Those advances included lewd phone calls, walking around naked in their presence, or groping their breasts, buttocks or genital areas, the women said.

Following The Post’s report, PBS and Bloomberg said they would halt distribution of Rose’s namesake interview program, which is produced by Charlie Rose, Inc., an independent television production company. Rose was also suspended by CBS News on Monday, less than 90 minutes after The Post’s story published.

In a statement provided to The Post on Monday — and later posted on social media — Rose said: “I deeply apologize for my inappropriate behavior. I am greatly embarrassed. I have behaved insensitively at times, and I accept responsibility for that, though I do not believe that all of these allegations are accurate. I always felt that I was pursuing shared feelings, even though I now realize I was mistaken.”

Rhodes, the CBS News president, wrote in his internal memo Tuesday that the network’s news operation “has reported on extraordinary revelations at other media companies this year and last. Our credibility in that reporting requires credibility managing basic standards of behavior. That is why we have taken these actions.

“Let’s please remember our obligations to each other as colleagues. We will have human resources support today and every day, and we are organizing more personal and direct training which you will hear about from senior management shortly.”

He added: “I’m deeply disappointed and angry that people were victimized — and that even people not connected with these events could see their hard work undermined. If all of us commit to the best behavior and the best work — that is what we can be known for.”
