Senator Elizabeth Warren subpoenas Nvidia CEO to testify before Congress on Trump administration chip policy implications.
Democratic Senator Elizabeth Warren called on Thursday for Nvidia CEO Jensen Huang and Commerce Department Secretary Howard Lutnick to testify following President Donald Trump's announcement of plans to greenlight sales of Nvidia's second-most advanced AI chip to China. Warren questioned the decision directly, asking, "Will Donald Trump muzzle his own Justice Department because he does not want Americans to know that he is selling out our national security?" Her request reflects concerns about Congressional oversight of policy changes permitting high-performance AI hardware exports, which Warren emphasized are critical to ensuring that advanced chips are not used in ways that could threaten U.S. technological leadership or compromise sensitive applications.
The United States government approved the export of Nvidia's H200 artificial intelligence chips to China, marking a significant shift in long-standing U.S. export controls on advanced semiconductor technology. The H200 is a high-performance AI accelerator used for complex machine learning and data center workloads. Under the new export framework announced by President Trump, the U.S. government collects a 25 percent share of the revenue from these sales. The policy partially reverses previous export restrictions that barred the shipment of H200-class GPUs to China over national security concerns, though the most advanced chips remain restricted.
White House spokesman Kush Desai defended the decision by distinguishing it from unregulated trade: "There's an obvious difference between chips being illegally smuggled to unknown buyers without regulatory oversight and chips being exported following national security inspections to specifically designated end users." Nvidia stated that all exports will comply with licensing requirements and that China represents a relatively small portion of its advanced chip business. The company also emphasized that H200 sales to China would still require a U.S. government license.
The move reflects broader tensions between economic opportunity and national security. Policymakers must balance commercial benefits with strategic considerations and the maintenance of technological leadership, particularly as AI hardware becomes more powerful and globally distributed. Congressional oversight, as demonstrated by Senator Warren's call for testimony, highlights lawmakers' role in ensuring that commercial interests do not compromise strategic priorities. The extent to which Congressional hearings, public scrutiny, or future policy changes might affect subsequent decisions on AI hardware exports remains unclear.
