Top Republican lawmakers in the House of Representatives have called on Nvidia chief executive Jensen Huang to brief Congress this month about a news report alleging he had a close relationship with a Chinese businesswoman who passed information to Beijing.
In a letter dated 4 November, seen by Reuters, Brian Mast, who chairs the House Foreign Affairs Committee, John Moolenaar, who leads the China Select Committee, and Intelligence Committee chair Eric Crawford asked Huang to give a closed-door briefing on 18 November about the report and Nvidia’s “security protocols against foreign adversary espionage”.
The report, published by The New York Times last month, said US authorities were investigating Alice Huang, a former executive of Singapore-based Megaspeed, which buys artificial intelligence chips from Nvidia. US authorities have scrutinised Megaspeed over suspicions it helped Beijing gain access to advanced AI chips that are barred from shipment to China.
The allegations in the report have not been independently verified, and no charges against either Huang or Alice Huang have been publicly reported. The letter does not accuse Nvidia of wrongdoing, but says the report raises “significant national security concerns regarding (China’s) access to sensitive U.S. technology and information”.
“It is vital that Congress determines the extent to which U.S. national security has been placed at risk,” the three chairmen wrote.
Nvidia did not comment on the letter itself, but said Huang talks with “thousands of customer executives every year” and stressed that cloud customers in Asia receive ordinary business information, not sensitive trade secrets or anything tied to US national security.
“We often receive updates from the U.S. government regarding parties and entities of concern and always act accordingly,” the company added.
The summons adds to the pressure on Nvidia’s China business, which is already caught between Washington’s export controls and Beijing’s restrictions. Separately, 600,000 Nvidia AI chips are stockpiled in Hong Kong as China withholds import approval, while US lawmakers continue to scrutinise how advanced American chips reach Chinese buyers.
