A women’s advocacy group is calling for the Republican National Committee to cut ties with Steve Wynn after allegations of sexual misconduct against him were reported Friday.

Wynn, a Las Vegas casino magnate, serves as chairman of the board of Wynn Resorts, as well as the finance chair of the Republican National Committee. Multiple women accused Wynn of pushing them to perform sexual acts on him and touching them inappropriately.

Wynn has denied the allegations, but one group, UltraViolet, has said he should step down from both posts.

“He is a predator of the worst kind who used his position of power to sexually coerce his female employees,” UltraViolet co-founder Nita Chaudhary said in a statement. “It is sadly no surprise that he keeps company with people like Donald Trump — a man who follows the same playbook of sexual abuse.”

The Wall Street Journal reported Friday that many of Wynn’s former female employees have detailed a pattern of sexual misconduct by Wynn that spans at least two decades.

One former manicurist who worked for Wynn said in 2005, he forced her to have sex with him.

The manicurist’s supervisor reported the misconduct to the casino’s human resources department. Wynn ultimately settled with the woman for $7.5 million.

Another woman, a massage therapist, said Wynn asked her to perform oral sex on him, which she rejected, and asked her to massage his penis during sessions, which the former employee said she felt forced to do given his position at the casino.

Wynn said the allegations stemmed from his ex-wife, Elaine Wynn.
