Nvidia CEO Jensen Huang declines a request from Sen. Elizabeth Warren to testify at a Senate hearing focused on the U.S. artificial intelligence industry. Warren invited Huang to appear Thursday before a Senate committee meeting to address Nvidia’s business involving China, including questions about how the company’s AI chips reach Chinese buyers and whether they could be used for military purposes. Multiple outlets report that Warren frames the inquiry around lawmakers’ scrutiny of AI chip sales to China and the effectiveness of U.S. export controls. Huang does not agree to testify, according to the reports. Instead, he offers an alternative arrangement, including a tour of Nvidia’s headquarters, as described by one outlet. The refusal keeps the discussion centered on oversight of export-related practices and the role of major AI hardware providers in international supply chains. The reports indicate that Huang’s response is a departure from Warren’s request that he answer questions publicly, potentially under oath, during the committee meeting.
