Senate panel seeks testimony from Nvidia's Huang and Commerce Secretary Lutnick

US Senate Banking Committee Chairman Tim Scott has requested testimony from Commerce Secretary Howard Lutnick and former Nvidia CEO Jensen Huang over national security concerns tied to Nvidia's China dealings and Huang's resignation. Huang stepped down from Nvidia following reports of a relationship with Alice Huang, whom US authorities suspect of spying for China. Lawmakers also criticized Lutnick over the administration's refusal to blacklist dozens of Chinese companies and oversight of Nvidia's exports. Scott said he may subpoena Huang if he doesn't appear voluntarily. Separately, three House committee chairs demanded closed-door interviews with Huang and Nvidia's general counsel for December 1-2, plus testimony from Commerce Under Secretary Jeffrey Kessler. China denies Alice Huang is a spy, and the Justice Department has not concluded on the matter.
