House Republican Committee chairmen ask Nvidia CEO Jensen Huang for closed-door China briefing

House Republican committee chairmen have asked Nvidia’s chief executive, Jensen Huang, to attend a closed-door briefing on November 18, 2026, at the Rayburn House Office Building in Washington, DC, according to a letter dated November 4, 2026.

The signatories are House Foreign Affairs Committee Chairman Brian Mast, House Select Committee on the CCP Chairman John Moolenaar, and House Permanent Select Committee on Intelligence Chairman Eric A. “Rick” Crawford. The letter told Huang to accept the November 18 date or propose another by November 11, 2026. The summons concerns alleged ties to a Chinese intelligence asset.

The letter went to Nvidia’s founder and chief executive at 2788 San Tomas Expressway, in Santa Clara, California. Its letterhead lists Gregory W. Meeks of New York and Sajit Gandhi; Meeks is the top Democrat on the committee, and Gandhi is the Democratic staff director.

The lawmakers asked Huang to discuss Nvidia’s defenses against espionage by foreign adversaries and his dealings with Alice Huang. Lawmakers have identified the Megaspeed executive as a suspected Chinese intelligence asset, the central claim driving the congressional inquiry. The committees seek a briefing to evaluate concerns and determine potential national security implications, though the letter includes no specific reports, no evidence of a breach and no proof that the company knowingly worked with Chinese intelligence. “Recent reports raise significant national security concerns regarding the PRC’s access to sensitive U.S. technology and information,” wrote Brian J. Mast, John Moolenaar and Eric A. “Rick” Crawford.

According to the lawmakers, PRC infiltration is central to their committees’ investigations this Congress, and so is access to advanced American technology. “It is vital that Congress determines the extent to which U.S. national security has been placed at risk,” Brian Mast, John Moolenaar and Eric Crawford said.

The New York Times said last month that US authorities had investigated Alice Huang, who once led Singapore-based Megaspeed. It amounted to earlier government scrutiny of the executive and her company. US authorities examined Megaspeed on suspicion that it helped Beijing obtain advanced AI chips barred from export to China. The Singapore-based cloud company has purchased billions of dollars of Nvidia chips, the business ties at the heart of the espionage concern.

According to the New York Times, American intelligence officials thought the Nvidia chief was the target of a Chinese spy operation. The report was the initial media report that prompted the lawmakers’ letter. Officials in Taiwan and Singapore were reportedly concerned that she might have shared sensitive Nvidia chip details.

Singapore said it had not shared any such information. Beijing called the spying allegations groundless speculation, saying it consistently rejects accusations that it targets American technology companies. According to the New York Times, President Donald Trump was briefed on the issue but did not act.

The company rejected the claims, describing customer meetings as a routine part of the CEO’s job and noting that Huang speaks with thousands of customer executives each year. It said Asian cloud customers of Nvidia receive ordinary business information, not sensitive trade secrets or material tied to American national security. The company said it regularly receives American government updates about concerning parties and entities and acts accordingly. The company expressed confidence that the American government would notify it if any individual were seen as a threat to American industry.

High-end semiconductor controls for artificial intelligence continue to tighten in Washington. US export controls prohibit Samsung and SK hynix from exporting High Bandwidth Memory to China, an existing restriction relevant to advanced chips. The joint request points to concerns reaching past Nvidia’s own security practices toward protecting American technology from foreign intelligence activities.

A security research firm found 32 of Nvidia’s B300 GPUs on the US export control list, seemingly deployed at China Telecom. Throwaway server chips equipped with HBM were moved from Hong Kong to China and de-soldered and repurposed for other uses, a route described as a smuggling route for memory components.

The Financial Times reported that Nvidia asked data center partners to reduce Chinese customer exposure and require that 51% of services go to non-Chinese companies. The request was part of Nvidia’s prior effort to reduce its China exposure.
