Republicans seek Jensen Huang testimony over national security concerns

Nvidia chief executive Jensen Huang resigned on Thursday after reports of affairs with a subordinate and with Alice Huang, a Singapore-based business executive accused of having links to Chinese espionage. Republican lawmakers are calling for him to testify to Congress, arguing that his relationship with Alice Huang and his advocacy for selling advanced chips abroad raise national security questions.

President Donald Trump said he had spoken to Huang, who told him he was unaware of Alice Huang’s suspected ties. Three Republican committee chairs had already asked Huang to attend a closed-door briefing, and the Wall Street Journal reported he was expected to co-operate, though it is unclear whether his resignation will affect that plan. Nvidia is valued at about $4 trillion and is central to the US effort to compete with China in artificial intelligence; the article says some of its chips are subject to US export restrictions.
