The board of Nvidia is preparing to oust CEO Jensen Huang amid growing concerns about his leadership of the AI giant following news of a second extramarital affair, according to the Wall Street Journal. 

In addition to his affair with a suspected Chinese spy, the New York Times reported Wednesday that Huang also had an extramarital relationship with Kimberly Powell, 48, Nvidia's vice president of healthcare, who reports directly to him.

Under Nvidia’s code of conduct, the Times reported, “employees are told to ‘avoid situations where our actions create conflict’ including ‘personal relationships,’ and the company states that it ‘promptly investigates reports of misconduct.’”
