NEW YORK ā€” CBS chief Les Moonves resigned Sunday, just hours after six more women accused the veteran television executive of sexual misconduct.

The resignation is effective immediately, CBS said in a statement posted on its website Sunday night.

The New Yorker magazine reported the latest allegations included Moonves forcing women to perform oral sex and retaliating when advances were turned away. Moonves acknowledged relations with three of the women but said they were consensual, adding he had never used his position to hurt the careers of women.

The network didn’t address the allegations directly, but said Moonves will donate $20 million to one or more organizations that support the #MeToo movement and equality for women in the workplace.

“The donation, which will be made immediately, has been deducted from any severance benefits that may be due Moonves,” the statement said.

Moonves again denied the allegations in a statement issued late Sunday night.

“Untrue allegations from decades ago are now being made against me that are not consistent with who I am,” he said.

“I am deeply saddened to be leaving the company,” Moonves added, calling it “an incredible privilege” to have worked for CBS.

“The best part of this journey has been working alongside the dedicated and talented people in this company,” he said.

CBS said the network’s chief operating officer, Joseph Ianniello, will take over Moonves’ duties as president and CEO until its board of directors can find a permanent replacement. For the time being Moonves’ role as chairman will remain vacant.

Hours before his resignation the New Yorker magazine reported sexual misconduct allegations from six additional women against Moonves, who was already under investigation for similar allegations made by six others.

As that investigation progressed it was widely reported that Moonves would leave the network shortly and was negotiating a severance package. CBS indicated Sunday, however, that no severance agreement has been reached.

“Moonves will not receive any severance benefits at this time (other than certain fully accrued and vested compensation and benefits); any payments to be made in the future will depend upon the results of the independent investigation and subsequent board evaluation,” the network’s statement said.

Moonves joined CBS as head of entertainment in 1995, and has been CEO of CBS Corp. since 2006, leading the CBS network, Showtime and other entities. CBS has spent much of his tenure as the nation’s most popular broadcast network, with hits such as “The Big Bang Theory” and “NCIS,” and its success has made Moonves one of the highest-paid and most powerful executives in the business.

One of Moonves’ accusers, Phyllis Golden-Gottlieb, also reported her accusations to Los Angeles police last year, but they weren’t pursued because the statute of limitations had expired. She said Moonves, while an executive at the Lorimar production studio in the late 1980s, pushed her head into his lap and forced her to perform oral sex.

At another time, she said an angry Moonves pushed her hard against a wall. When she resisted later advances, she began to be frozen out at the company, she said.

“He absolutely ruined my career,” she told the New Yorker.

Another woman, Jessica Pallingston, said Moonves forced her to perform oral sex on her first day working as his assistant at Warner Bros. productions. Other women told the magazine of unwanted touching or advances.

In a statement to the magazine, Moonves said the “appalling accusations” are untrue, but he acknowledged consensual relations with three of the women before he started working at CBS.

“I have never used my position to hinder the advancement or careers of women,” he said. “In my 40 years of work, I have never before heard of such disturbing accusations. I can only surmise they are surfacing now for the first time, decades later, as part of a concerted effort by others to destroy my name, my reputation and my career. Anyone who knows me knows that the person described in this article is not me.”

The organization Time’s Up, which fights accusations of sexual misconduct, said the women had made “bone-chilling” accusations against Moonves. “We believe them,” Times’ Up said in a statement early Sunday. The group said the CBS board has a responsibility to rid the company of a toxic culture toward women.

“A $20 million donation is a first step in acknowledging that you have a problem,” Time’s Up said in a statement directed at CBS after Moonves’ departure. “But it is far from a solution.”

It urged the network to use all the money it had allocated for Moonves’ severance to “instead help women.”

“Cleansing the company of this toxic culture demands real systemic change,” the group tweeted.

Ianniello, who will be replacing Moonves on at least an interim basis, joined CBS in 2005 and has been COO since 2013. He has steered top projects such as the CBS All Access and Showtime streaming services.
