Russell Simmons is stepping down from his companies in the wake of an accusation of harassment and sexual assault.

According to CNN Simmons, the founder of hip-hop music label Def Jam Recordings and CEO of Rush Communications, released a statement on Thursday after screenwriter Jenny Lumet accused him of forcing her to have sex with him in 1991.

The statement said:

"I have been informed with great anguish of Jenny Lumet's recollection about our night together in 1991," Simmons said in a statement. "I know Jenny and her family and have seen her several times over the years since the evening she described. While her memory of that evening is very different from mine, it is now clear to me that her feelings of fear and intimidation are real. While I have never been violent, I have been thoughtless and insensitive in some of my relationships over many decades and I sincerely and humbly apologize."

CNN reports that on November 19, the the Los Angeles Times published a report that detailed allegations of sexual misconduct made against director Brett Ratner and Simmons.
