Longtime CBS chief executive Les Moonves is stepping down as he faces a new round of sexual harassment allegations, the network confirmed Sunday.The network announced Sunday Moonves is leaving, effective immediately. He and the network will also donate $20 million to organizations that support the #MeToo movement and equality for women in the workplace.The network said current Chief Operating Officer Joseph Ianniello will serve as president and acting CEO while the board searches for a permanent successor.Before his resignation, there were reports that Moonves could be due millions even if he were to leave. But the company said the $20 million donation will be deducted from any possible severance payments and that the rest of any potential severance benefits are being withheld pending an investigation into Moonves' conduct.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.The resignation comes after new claims of sexual misconduct against Moonves. The New Yorker on Sunday reported the allegations made by six new women.Moonves acknowledged relations with three of the women but said they were consensual, and that he had never used his position to hurt women's careers.Six other women had accused Moonves of misconduct in another New Yorker article published last month.Even before the new allegations came to light on Sunday, CBS' board was reportedly discussing terms of Moonves' exit.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.
