GoKawiilBEIJING, CHINA - MAY 14: Nvidia CEO Jensen Huang waves as he prepares to depart the Great Hall of the People on May 14, 2026 in Beijing, China.
Nvidia CEO Jensen Huang is being invited to testify before the Senate Banking Committee on June 11 as Sen. Elizabeth Warren, D-Mass., sharpens her focus on the chipmaker's China sales, export controls and role at the center of the global AI boom.
"Appearing as a witness will give you an opportunity to testify about NVIDIA's views on U.S. export control laws and regulations and NVIDIA's business in China," Warren wrote in a letter first obtained by CNBC. She asked Huang to confirm his attendance by Monday.
Nvidia's chips power many of the data centers behind advanced AI models, making the company one of the biggest winners of the artificial intelligence surge. But that dominance has also drawn growing attention from lawmakers and national security officials who warn advanced U.S. chips could be used by China to strengthen its military and surveillance capabilities.
The Biden and Trump administrations have both moved to restrict China's access to advanced AI chips, while Nvidia has argued that overly broad limits could damage U.S. competitiveness and push customers toward foreign alternatives.
The Senate push coincides with a move by Republicans on the House Energy and Commerce Committe who are separately calling for an investigation into what they say are China's efforts to impede U.S. AI and data-center development.
Warren previewed her concerns Wednesday on CNBC's "Squawk Box," saying she is worried U.S. companies are profiting from technology sales that could weaken U.S. security.
"The Chinese, in effect, buy our stuff, and American companies make a profit doing that," Warren said. "But it certainly undermines our long-term security."
She said the concern is especially acute because the chips at issue are "not just chips to help the AI industry in general."
"In China, these are chips that are actually used for military purposes," Warren said.
