US commerce secretary faces scrutiny over Nvidia CEO's links to alleged China spy

US Commerce Secretary Howard Lutnick is being investigated after a classified warning tied to Nvidia CEO Jensen Huang's connections with Alice Huang, suspected of spying for China. Reuters uncovered that a blacklisted Chinese defence university acquired restricted Nvidia AI chips. The relationship reportedly enabled shipments worth over seven billion dollars via firms including Singapore's MegaSpeed. A confidential memo drafted under US Secretary of State Marco Rubio circulated before President Trump's China visit. Despite security concerns, Trump defended Huang, leading to calls for a closed-door briefing and a shareholder lawsuit against Nvidia and Huang.
