Congress weighs subpoena for Nvidia's Jensen Huang as lawmakers call on him to resign

The background is that Huang acknowledged on Sunday, 9 November, a relationship with a woman who, according to news reports, US intelligence concluded was a Chinese spy. She is described by lawmakers as an alleged spy and she is not related to Huang. Representative Suhas Subramanyam, the top Democrat on a House Oversight subcommittee, said she was allegedly helping smuggle chips into China at an alarming rate, an assertion that has not been tested in court. Nvidia's board opened an independent investigation on 9 November. The board has said it sees no sign that company secrets were lost.

Who wants him to go

Senator Kevin Cramer, a North Dakota Republican, said Huang should resign as a matter of his own conscience, arguing that he is vulnerable to extortion or blackmail, which he called a national security risk. Subramanyam said Huang should resign from Nvidia, and Representative Don Bacon, a Nebraska Republican, said the chief executive should step down, in part because he believes Huang let himself be compromised by the Chinese government.

Nvidia has announced no decision on Huang's position, and its board's statement so far is that it sees no sign of lost secrets.

The export-control fight and what comes next

The case has landed in the middle of a dispute about chip exports to China. Congress has not yet passed this year's National Defense Authorization Act, and lawmakers may attach bills to tighten controls on AI chips, among them the AI Overwatch Act, the MATCH Act and the Chip Security Act. Senators Elizabeth Warren, who is due to chair the Banking Committee, and Jim Banks urged that the AI Overwatch Act be included. Huang has opposed strict export controls on AI chips to China and travelled to China with President Donald Trump in May. Representative Jay Obernolte said he hoped the controversy would not derail the export-control talks.

A congressional subpoena is a legal order to appear or to hand over documents, and a person who ignores one can be referred for contempt proceedings. That is why the chairmen's statements about intent matter: a voluntary closed-door briefing could be arranged on any date, while a subpoena would set a legal obligation. With the 18 November deadline falling the day after the earnings report, Huang's lawyers and the company's board have a few days in which to decide how to answer.

China's government has rejected the spy allegation. Its foreign ministry called it a smear on 9 November and declined to comment on a reported figure of 600,000 chips said to have reached Chinese buyers. Nvidia's board, for its part, said at the start of its own review that it saw no sign that company secrets were lost, and the committees have not published evidence of their own. That leaves the central claims, about the woman's role and any chip diversion, as allegations that have not been tested in court or confirmed by an official finding.

Timing matters on both sides. Democrats are expected to take control of both chambers of Congress in January and plan investigations that could centre on Nvidia, while the Republican committee chairs lose their gavels then and any subpoena they issue would expire with the session.

For investors and customers, the next date is Nvidia's earnings report on 17 November, a day before the deadline to testify. The controversy has weighed on Nvidia's shares, which recovered somewhat on 12 November after strong results from the AI cloud company CoreWeave, whose revenue rose 168% to $3.661 billion in the third quarter. Whether Huang appears on 18 November, is subpoenaed, or the board takes a decision first will show how serious the risk to the company's leadership is.
