Bill Gates’ alleged affair with a Microsoft employee is in the spotlight today as details start to emerge about questionable behavior before his divorce announcement.

Bill Gates was accused of having an affair with a Microsoft employee, leading to an internal investigation into Microsoft’s co-founder and board director just before Gates stepped down. The alleged affair was brought to the board’s attention back in 2019 when a Microsoft engineer wrote a letter outlining the details of her inappropriate relationship with the tech mogul, citing various sexual encounters over the years.

In the letter, she requested that her job change at Microsoft and that Bill Gates’ wife be allowed to read the letter. Though it isn’t known whether Melinda Gates received the letter to read, the company quickly took action, hiring a law firm to investigate the relationship.

While the evidence has not been released, the New York Post claims that members of the board were concerned about the initial outcome of the investigation and wanted Bill Gates to step down from his executive role at Microsoft. This didn’t happen. Gates was re-elected to Microsoft’s board during the annual shareholder meeting.

Bill Gates eventually resigned from his director position at Microsoft in2020, just before the investigation was completed. He explained that his interest in philanthropy was taking precedent. Some claim, though, that the resignation was directly related to the investigation into his affair. 

“Microsoft received a concern in the latter half of 2019 that Bill Gates sought to initiate an intimate relationship with a company employee in the year 2000,” a Microsoft spokesperson explained. “A committee of the Board reviewed the concern, aided by an outside law firm, to conduct a thorough investigation. Throughout the investigation, Microsoft provided extensive support to the employee who raised the concern.”

spokesperson for Gates admitted that “there was an affair almost 20 years ago which ended amicably.” However, the spokesperson said that “Bill’s decision to transition off the board was in no way related to this matter. In fact, he had expressed an interest in spending more time on his philanthropy starting several years earlier.” The statement Gates made in March 2020 expressing his decision to leave the company’s executive board explains similar reasoning.

This isn’t the first incident raising questions about Bill Gates’ behavior. A New York Times article reported that Gates was known for fraternizing with employees on an unprofessional level, where he “developed a reputation for questionable conduct in work-related settings.”

The Times said that “Mr. Gates pursued women who worked for him at Microsoft and the Bill and Melinda Gates Foundation,” and this was “on at least a few occasions.” The controversial reports regarding Bill Gates might have revealed the true man behind the billion-dollar fortune.

However, Gates’ spokesperson fought back against what they claim were “untruths published about the cause, the circumstances and the timeline of Bill Gates’ divorce,” saying that “it is extremely disappointing.” The spokesperson claims that the $130 billion divorce is for completely unrelated reasons and that and “claim of mistreatment of employees is also false,” explaining that “the rumors and speculation surrounding Gates’ divorce are becoming increasingly absurd and it’s unfortunate that people who have little to no knowledge of the situation are being characterized as ‘sources.'”

Bill and Melinda Gates recently filed for divorce after nearly 25 years of marriage. Melinda Gates “decided that it was best for her to leave her marriage as she moved into the next phase of her life.” Also, earlier this month, it was revealed that Bill Gates went on yearly excursions with his ex-girlfriend, Ann Winblad, even during his marriage to Melinda.
