U.S. Senator urges Nvidia CEO to testify over planned approval of AI chip sales to China

U.S. Senator Elizabeth Warren called for Nvidia CEO Jensen Huang and Commerce Secretary Howard Lutnick to testify regarding President Trump’s planned greenlight for sales of Nvidia’s H200 AI chip to China. The request highlights ongoing policy volatility around export controls for advanced AI hardware and the national-security debate over compute access. For Nvidia and the broader semiconductor ecosystem, such political moves can quickly reshape revenue outlooks, customer allocation strategies, and compliance risk. For AI developers and cloud providers, the policy direction influences where frontier training and inference capacity can be deployed—and which regions face structural compute constraints.
