US lawmakers demand answers on Nvidia CEO's affair with alleged Chinese intelligence link

US lawmakers are demanding answers from Nvidia CEO Jensen Huang after he admitted to an affair with a woman accused of working for Chinese intelligence, raising national security concerns. Nvidia says no secrets were compromised, but experts question what sensitive information may have been exposed. The woman, Alice Huang, is a former executive at Singapore-based Megaspeed, which bought over $4.8bn worth of Nvidia chips in two years and has been investigated for allegedly helping Chinese firms access restricted chips. US intelligence believes she was recruited to influence Jensen Huang to push for looser chip export restrictions to China, though no evidence has been made public. Republican leaders have requested a closed-door briefing, with a subpoena threatened if he does not respond. President Donald Trump has stood by Huang, calling him an "honourable guy," while some lawmakers have called for his resignation. China has denied the espionage allegations as groundless.
