Nvidia CEO Jensen Huang is already under scrutiny after admitting to an affair with a woman accused of being a Chinese spy. Now, the New York Times reports that Huang is also suspected of having another affair, this time with a direct report at the company.

The newspaper reported Wednesday that Huang is accused of having another extramarital affair with Kimberly Powell, Nvidia's vice president of health care. Powell, like Huang, is married, according to the outlet. The Times says it was told of the alleged affair by five employees at the company. The sources said that Huang and Powell were captured on video "being affectionate at a San Jose, Calif., hotel" during a conference earlier this year.

Like many companies, Nvidia has rules discouraging superiors from having relationships with employees in subordinate roles, the Times notes. The company's board has initiated an investigation into Huang's publicly admitted affair.

Additionally, two House Republicans said Wednesday that Congress is gearing up to subpoena Huang over the spy allegations if he doesn't voluntarily respond to their summons to a closed-door briefing. Late Wednesday, after the reports of the second affair were published, the Wall Street Journal reported that the Nvidia board was preparing to oust its founder.
