Nvidia chief executive Jensen Huang is facing fresh allegations of a second affair, this time with a senior executive at the chip maker, as the company's board meets to decide whether he should keep his job. The New York Times reported on Wednesday that Mr Huang had a relationship with Kimberly Powell, Nvidia's vice president of healthcare and one of his roughly 60 direct reports, citing five people who have worked at the company. Ms Powell has been with Nvidia for more than 18 years.
