Jeffries Seeks Full Briefing on Nvidia as Shares Fall 4.3% on November 9
Key Facts
U.S. House Democratic Leader Hakeem Jeffries called for a full congressional briefing on Nvidia after reports that the company’s chief executive, Jensen Huang, was targeted in an action attributed to a foreign intelligence service. Jeffries said on November 9 that lawmakers needed more information to understand what happened. He added: "We’re going to need a full briefing, specifically as it relates to Nvidia, so that we can all understand what happened." The request places the company at the center of security and political scrutiny linked to Huang, as debate in Washington broadens to include controls on exports of AI chips to China. The call came ahead of a classified briefing scheduled for later that day.
Jeffries’ office said he had not received a full briefing on the Huang matter before the scheduled classified session. The lawmaker’s official website quoted him as saying: "I have not been fully briefed on this matter. However, we have a classified briefing later today." The session comes as congressional committees and U.S. officials examine security issues related to the company and its ties to China. Nvidia has announced an independent investigation into reports concerning the targeting of Huang, and the CEO said he would cooperate fully. Huang said: "I support the investigation and will cooperate fully."
Alongside scrutiny of the reports concerning Huang, the legislative debate is focused on limiting China’s access to advanced chips and semiconductor manufacturing equipment. Jeffries said he strongly supports restrictions on U.S. chip sales to China in the final version of the annual defense bill. The Senate version includes provisions giving Congress broader authority over exports of AI chips to China and urging U.S. allies to restrict sales of semiconductor manufacturing equipment to the country. The proposals also require companies to track chips abroad to curb smuggling. Washington is considering including three measures in the defense authorization bill for fiscal year 2027, which began in October 2026.
The measures include the AI Overwatch Act, which expands congressional authority over exports of advanced chips; the Chip Security Act, which requires chip tracking to combat smuggling; and the MATCH Act, which presses U.S. allies to restrict sales of chipmaking equipment to China. The House Foreign Affairs Committee approved all three measures earlier in 2026, and they were later included in the Senate’s defense bill package, according to Reuters. In January, the House Foreign Affairs Committee approved the AI Overwatch Act, which requires licenses for exports, re-exports or transfers within countries of certain high-performance AI chips to countries designated as a concern. The bill gives Congress a direct oversight role in decisions on exports of these chips. Jeffries said he wants chip restrictions included in the final version of the defense bill.
In a separate oversight track, three Republican House committee chairs asked Huang to provide a closed-door briefing on November 18 on a report about his relationship with a Chinese businesswoman and Nvidia’s security protocols. The chairs of the Foreign Affairs, China and Intelligence committees requested a joint briefing on that date, asking Huang to accept the date or propose an alternative by November 11. The Republican request reflects a separate move from Jeffries’ call for a congressional briefing on reports concerning the targeting of Huang. Republican Senator Jim Banks and Democratic Senator Elizabeth Warren also said the CEO had confirmed a relationship with someone suspected of spying for China’s intelligence service. The senators urged Congress to pass the AI Overwatch Act as part of the defense bill.
Nvidia said it had opened an independent investigation into the reports, while its board said it saw no reason to believe national security or company secrets had been compromised, adding that the investigation would review the available information. The Associated Press quoted the board as saying it "sees no reason to believe" a breach had occurred, while pledging to review all available information. China’s Foreign Ministry rejected the espionage allegations, calling them a smear campaign against Beijing. The White House did not comment on the proposed legislative measures, according to Reuters. An industry council that includes Nvidia objected to the measures, saying they could weaken U.S. competitiveness and complicate export control policy.
The political debate coincided with a 4.3% drop in Nvidia shares in Monday’s November 9 session, according to the Associated Press, amid the investigation into reports concerning Huang. The stock closed at $178.67, according to EL7 data. The agency said the shares fell 23% in the 30 days ended November 9, as part of a broader selloff in AI stocks that accelerated in early October. The briefing requested by Republicans from Huang remains scheduled for November 18, and he is due to accept the date or propose an alternative by November 11. The proposed restrictions on chip exports remain under consideration as part of the annual defense bill process.
