House Republicans Ask Nvidia's Jensen Huang for Closed-Door Briefing on Espionage Concerns

The letter, dated November 4, was signed by Brian Mast, chairman of the House Foreign Affairs Committee; John Moolenaar, who leads the House Select Committee on China; and Eric Crawford, chairman of the House Intelligence Committee. The lawmakers said a New York Times report published last month raised national security concerns about China's access to sensitive US technology and information.

The request means that leaders of three committees covering foreign policy, China and intelligence now want Huang to answer questions in person. That brings the head of the world's most valuable AI chip supplier into a congressional inquiry that has so far played out in the press. Nvidia's sales to China and to intermediaries in Southeast Asia are already under close watch in Washington because of export controls on advanced AI processors.

The Times reported on October 29 that US intelligence agencies had concluded that Alice Huang, also known as Huang Le, was gathering information for the Chinese government. She is a Chinese national and a former executive of Megaspeed, a Singapore-based data centre operator that buys Nvidia chips. Citing people briefed on classified surveillance, the paper said she had built a close relationship with the Nvidia chief executive. It also reported that President Donald Trump was briefed on the findings in 2025 and did not act on them.

US authorities had already been examining Megaspeed over suspicions that it helped Beijing obtain advanced AI chips barred from export to China. According to the Times report, a Malaysian affiliate of Megaspeed bought at least $4.8 billion of equipment containing Nvidia technology between June 2024 and February 2026. Allegations that any of that hardware was diverted to China have not been publicly substantiated.

Nvidia did not comment on the lawmakers' letter. In its earlier response to the Times report, the company said Huang meets thousands of customer executives each year. It said cloud customers in Asia receive ordinary business information rather than Nvidia trade secrets or anything bearing on US national security, and that it acts on US government updates about entities of concern. Huang has rejected suggestions that his dealings with Megaspeed were improper. He has described the relationship as a normal one and said Nvidia checked GPU deployments to see whether any processors had been diverted.

Others named in the story have also responded. Singapore's Ministry of Home Affairs said on October 31 that it had not conducted any investigation into Alice Huang's alleged intelligence links or her relationship with Jensen Huang, though it confirmed that investigations into Megaspeed itself are continuing. Megaspeed's current management said it had hired outside legal counsel to look into the claims and would cooperate with US authorities. A spokesperson for China's foreign ministry, Guo Jiakun, called the reports unsubstantiated.

The letter asks for information and does not accuse Huang of wrongdoing. The public reporting so far does not show what information Alice Huang is alleged to have passed on, whether it included confidential Nvidia material, or whether any technology reached China through Megaspeed. The committees have not said whether Huang has agreed to the November 18 session.
