Three House committee chairs have asked Nvidia CEO Jensen Huang to attend a closed-door briefing on November 18, 2026, and set November 11 as the deadline to accept that date or suggest another. House Foreign Affairs Committee Chairman Brian Mast says he may subpoena Huang if he does not respond by the deadline, Tom’s Hardware reports, citing ABC News. The request is not itself a subpoena, and the committees have not said that one has been issued.
The letter was sent by Mast, House Select Committee on China Chairman John Moolenaar and House Intelligence Committee Chairman Rick Crawford. They want to discuss Huang’s interactions with Megaspeed executive Alice Huang, whom the committee letter describes as a publicly reported Chinese intelligence asset, as well as Nvidia’s security protocols against foreign espionage.
What the committees want to examine
The chairmen say reports have raised concerns about China’s access to sensitive U.S. technology and information. Their letter says the committees are investigating possible Chinese infiltration and access to advanced U.S. technology, and that they want to determine whether U.S. national security has been put at risk. The stated concerns are the committees’ rationale for requesting a briefing; the letter does not establish that Nvidia’s security was breached or that Huang acted improperly.
The requested meeting would be joint and closed to the public. The committees have asked Huang to appear on November 18, or to provide an alternative date by November 11. The briefing’s scope, beyond Huang’s interactions with Alice Huang and Nvidia’s security measures, is not specified in the committee announcement.
The subpoena threat is conditional
Mast’s warning, as reported by Tom’s Hardware citing ABC News, makes the response deadline the immediate point to watch. A subpoena could compel Huang to appear, but the committee announcement describes only a request for a briefing and a conditional warning from Mast. It does not say whether Huang or Nvidia accepted the proposed date, offered another date or responded to the letter.
Why it matters
For Nvidia shareholders and customers, the confirmed development is a request for a congressional briefing, not a finding that the company’s systems were compromised. Whether Huang responds—or whether Mast follows through on the subpoena warning—remains unknown.
