Mr. Huang, Nvidia’s chief executive, is already facing scrutiny over an affair with a Chinese businesswoman who U.S. intelligence determined was a Chinese spy.
The relationship, which has not been previously reported, was with Kimberly Powell, Nvidia’s vice president of health care, said the people, who spoke under the condition of anonymity to describe sensitive information. Under Nvidia’s code of conduct, 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.” Many corporations have policies against managers having relationships with subordinates.
