Nvidia CEO Jensen Huang has declined an invitation from Sen. Elizabeth Warren to testify before a Senate committee hearing this week focused on artificial intelligence, export controls, and America's technological competition with China, NBC News reported.

The hearing, scheduled for Thursday before the Senate Committee on Banking, Housing, and Urban Affairs, will examine AI's role in U.S. innovation, affordability, and global competitiveness.

Warren, a Massachusetts Democrat, had sought Huang's testimony as lawmakers scrutinize Nvidia's business activities in China and the company's stance on restrictions governing exports of advanced American AI technology.

"NVIDIA sits at the center of some of the most important questions facing our country about artificial intelligence, economic competition, and national security," Warren said in a statement criticizing Huang's decision not to appear.

"If Mr. Huang has time to attend a $1 million-a-head dinner at Mar-a-Lago and fly across the world to meet with President Xi Jinping of China, he should be able to find time to answer questions from Congress," she added.

Nvidia, whose market capitalization exceeds $5 trillion, has become one of the world's most influential technology companies as demand for AI chips has surged. Its processors and hardware power many of today's leading artificial intelligence systems.

In a letter to Warren, Huang said he was unable to attend the hearing but expressed support for the committee's work.

"I am unable to attend, but appreciate the committee's focus on these important issues," Huang wrote. "American leadership in AI technologies cannot be taken for granted, but we are confident in the future and believe in the American system."

Huang also invited Warren and other committee members to visit Nvidia's headquarters in Santa Clara, California, to discuss the company's technology and the broader U.S. AI ecosystem.

The dispute highlights growing tensions in Washington over how aggressively the United States should restrict exports of advanced AI technology to China and other geopolitical rivals.

Huang, who serves on President Donald Trump's Council of Advisors on Science and Technology, has repeatedly argued that American companies should be allowed to compete globally, including in China, while maintaining U.S. technological leadership.

"We should ensure that American companies have the best and the most and first," Huang told reporters in December, adding that the U.S. should offer "the most competitive chips we can to the Chinese market."

Warren has sharply criticized that position, arguing that broader access to advanced U.S. chips could strengthen China's military capabilities and weaken America's strategic advantages.

The debate comes as the Commerce Department recently moved to close what officials described as a significant loophole in export-control regulations that may have allowed companies to ship advanced AI chips through countries not directly subject to restrictions.

Lawmakers from both parties have increasingly focused on AI-related export controls as Congress considers multiple proposals that would tighten restrictions on sales of advanced semiconductors and chipmaking equipment to China and other foreign adversaries.

Supporters of stricter controls argue that advanced AI chips have significant military and intelligence applications and require close government oversight. Others contend that limiting overseas sales could undermine American innovation and allow foreign competitors to gain market share.

Scheduled witnesses for Thursday's committee meeting include Mike Flynn of the Information Technology Industry Council, David Feith of the Hudson Institute, Will Rinehart of the American Enterprise Institute, and Sarah Myers West of the AI Now Institute.
