Three committees seek Huang interview as Congress moves to tighten chip restrictions

Key Facts

U.S. scrutiny of Nvidia’s ties to China has widened, with three House committees requesting a closed-door interview with its chief, Jensen Huang, on December 1, while Senate Banking Committee Chairman Tim Scott asked him to testify. Scott said he would consider subpoenaing Huang if he did not appear voluntarily, indicating that the testimony request has not yet become a legal subpoena. Concerns raised by recent reports center on national security and the protection of sensitive U.S. technology. The House committees also requested an interview with Nvidia’s general counsel on December 2 and asked Commerce Under Secretary Jeffrey Kessler to testify at a December 3 hearing. The requests place the company and its executives at the center of a broader debate over oversight of semiconductor exports to China.

These steps follow an earlier effort by the House Foreign Affairs Committee to obtain a closed-door briefing from Huang. On November 4, the committee requested that he provide a briefing behind closed doors, and a spokesperson for its chairman said the committee could turn to a congressional subpoena if he did not respond. The move to request specific interviews and a hearing reflects lawmakers’ growing interest in the matter across different committees, although the requests announced so far remain efforts to secure voluntary appearances. In the Senate, Scott linked the possibility of a subpoena to Huang’s failure to appear voluntarily, while the House Foreign Affairs Committee chairman said he was open to a similar step if Huang did not respond. The available information did not confirm that a legal subpoena had been issued to Huang.

The concerns stem from allegations about Huang’s relationship with a businesswoman whom U.S. authorities suspect of spying for the Chinese government, alongside reports of two extramarital relationships. Reuters reported that Huang resigned from Nvidia after those reports emerged, and that one of the relationships was with the woman under suspicion. But the U.S. Justice Department has not yet reached a conclusion on whether Alice Huang is a spy, Reuters reported. The matter therefore remains within the scope of suspicion and investigation, rather than a settled finding by authorities. Earlier in November, Nvidia’s board launched an investigation into the possibility that Huang was targeted in a foreign intelligence operation, led by independent directors and assisted by outside legal counsel. The internal investigation adds another layer of scrutiny to lawmakers’ requests, while the allegations remain under examination.

The debate extends from Huang’s conduct to chip export policy, as lawmakers from both parties push for tighter restrictions on China’s access to advanced AI chips. House Speaker Mike Johnson said there was growing consensus in Congress on limiting semiconductor exports to China. Reuters reported that Huang had pushed to preserve access to the Chinese market, while Nvidia’s most advanced chips remained subject to U.S. efforts to restrict China’s access to them. This comes as Nvidia said in an August statement that its revenue from chip sales to Chinese data centers was close to zero and that it did not expect this to change in the third quarter. This background shows that the political debate is not limited to current sales, but also covers the rules governing potential future sales of advanced chips.

Nvidia shares closed at $166.19 on November 12, down from $173.73 in the previous session, according to EL7 data. Reuters said the stock fell 7.6% on Thursday, as investors worried about the effect of Huang’s resignation on the AI sector. The session’s share-price move was thus linked to investors’ concerns about the resignation’s implications for the sector, not solely to the committees’ requests. Markets are tracking the matter as developments involving the company’s leadership intersect with the debate over chip exports to China. Investors were awaiting the release of the Producer Price Index on Friday, November 13, which could offer signals about the inflation outlook. That economic release was among the market factors watched in the next session, alongside developments at Nvidia.

Attention is turning to whether Huang will attend the interviews requested by the House committees and to the December 3 hearing at which the committees requested Kessler’s testimony. The case could also have broader implications for U.S. chip export rules; Reuters said it could have far-reaching consequences for export policy and the wider AI ecosystem. The AI Overwatch initiative aims to increase Congress’s role in reviewing any changes to export rules, which could make it harder for future administrations to ease restrictions on sales of advanced chips to China. At the same time, lawmakers from both parties are pushing to tighten restrictions on China’s access to advanced AI chips. Decisions on appearances and the next legislative steps remain key milestones in political and regulatory scrutiny of Nvidia.
