House Republicans seek Nvidia CEO testimony, threaten subpoena over China spy allegations

House Republicans are unlikely to accept Nvidia CEO Jensen Huang sending his general counsel to a closed-door briefing about alleged ties to a Chinese spy, and they may issue a subpoena if he declines to appear personally. The request stems from a New York Times report alleging Huang had a close relationship with a Chinese businesswoman who passed information to Beijing. House Foreign Affairs Chairman Brian Mast is open to subpoenaing Huang if he doesn't respond, with a Wednesday deadline set by lawmakers. The allegations have heightened congressional concerns over whether US export controls on Nvidia's advanced AI chips are strong enough to prevent sensitive technology from benefiting China, amid a broader US-China race to develop powerful AI systems. Nvidia has not commented.
