Three congressional committee chairs have requested NVIDIA CEO Jensen Huang to attend a closed-door briefing on issues including espionage defense, and asked him to respond by November 11th on whether he will accept the briefing or propose an alternative date. This follows media reports alleging that a U.S. intelligence memo concerns connections between the NVIDIA CEO and executives at Singapore-based Megaspeed. NVIDIA responded that its engagements with customers are routine commercial business and involve no sharing of classified information.
