A top Republican Party official and casino mogul is denying a report that he assaulted female employees in a decades-long pattern of abuse.
Steve Wynn is accused of harassing massage therapists and forcing one staff member to have sex with him, reports the Wall Street Journal.
“The idea that I ever assaulted any woman is preposterous,” Mr Wynn said in a statement on Friday afternoon.
He blamed his ex-wife, who he is fighting in court, for the “slander”.
“The instigation of these accusations is the continued work of my ex-wife Elaine Wynn, with whom I am involved in a terrible and nasty lawsuit,” the 75-year-old billionaire said in a statement that his public relations team sent to the BBC.
Following the report, Wynn Resorts stocks dropped by more than 10%.
Regulators in Massachusetts, where Mr Wynn is building a casino outside Boston, say they are “taking very seriously the troubling allegations”, and have launched a review of his actions.
“The suitability and integrity of our gaming licensees is of the utmost importance, and ensuring that suitability is an active and ongoing process,” a spokeswoman said in a statement.
