Casino icon Steve Wynn is suing his former company and Massachusetts gaming regulators to block the release of a report into his alleged sexual misconduct.

On Wednesday, Steve filed suit in Las Vegas against Wynn Resorts and the Massachusetts Gaming Commission (MGC) to prevent the release of an investigative report the MGC commissioned to determine what Wynn execs knew of the allegations against Steve and when they knew it.

The MGC probe was launched following the emergence in January of multiple allegations of Steve sexually harassing Wynn’s female staff. Evidence subsequently emerged suggesting the company was aware of a $7.5m paternity suit settlement involving a former manicurist at Wynn Las Vegas yet failed to disclose this info to the MGC during license suitability vetting for Wynn’s in-development Encore Boston Harbor casino.

The report was supposed to be made public in December but Steve, who resigned his CEO/chairmanship of Wynn Resorts in February, is hellbent on preventing that release. Steve argues that Wynn improperly shared “scores of documents” with the MGC that are protected by attorney-client privilege.
