"We are not aware of any criminal investigation of the company and no agency has notified the company that it is under any investigation," a Wynn spokesman told CNBC. "The fact that information is requested from us by a governmental agency in no way implies the accusation of any wrongdoing by the company."
The Nevada U.S. Attorney's Office told CNBC that it is not able to confirm or deny any investigation into Wynn Resorts, citing Department of Justice policy.
According to the report, Wynn Resorts is the third major Las Vegas casino firm to come under money-laundering investigation recently.
