World Wrestling Entertainment's board of managers  is investigating a $3 million deal that CEO Vince McMahon paid to a woman over an alleged extramarital affair, the Wall Street Journal reported Wednesday, citing documents and people familiar with the matter.

The agreement, signed in January, was designed to prevent the woman, who is an assistant to the company's attorney, from speaking about her relationship with McMahon or speaking critically about the CEO, the paper added.

A WWE spokesperson told the paper that the company was cooperating with the onboard investigation and that the relationship between McMahon and the woman was delicate.

McMahon, 76, is married to Linda McMahon, who was WWE boss and head of small business administration under former WWE Hall of Fame official Donald Trump. The report says the onboard investigation began in April and uncovered confidentiality pacts related to allegations of misconduct by other women who have worked at WWE. The paper added that report added that the deal includes McMahon and WWE senior talent director John Laurinaitis, who fights under the Johnny Ace moniker.

The board detained Simpson Thacher & Bartlett LLP, a New York-based law firm, to investigate, a source told the Journal. The company did not immediately answer to a request for comment from NEWS.

McMahon's attorney, Jerry McDevitt, was not immediately available for comment. McDevitt told the Journal that the former team member had not made any harassment allegations against McMahon. He also said the paper wrote that WWE had not paid him any money.

The news comes at a significant time for the wrestling and entertainment company. In May, CEO Stephanie McMahon, daughter of Vince and Linda McMahon, took time off from most of her responsibilities at the company. "WWE is a lifelong legacy to me and I look forward to returning to the company I love after taking time to focus on my family," he wrote on Twitter at the time.

WWE has also been the subject of speculation about its possible sale and media rights. There are deals with Fox, USA Network, Hulu, and Peacock streaming service NBCUniversal. The deal with Hulu expires this year.
