Warren and Coons Seek Preservation of Records on Nvidia Chip Exports to China by November 17
Key Facts
Senators Elizabeth Warren and Chris Coons asked the Trump administration to preserve records related to Nvidia’s exports of advanced AI chips to China, a move focused on the security risks associated with those exports. The Senate Banking, Housing and Urban Affairs Committee said the letter requests “the preservation of all documents, communications, records and other materials relating to Nvidia’s exports of advanced AI chips to China.” The senators also requested confirmation that preservation instructions had been issued and a briefing for Congress on potential national security risks. They set November 17 as the deadline to receive written confirmation that the instructions had been issued. The request comes as lawmakers in the House are also seeking a briefing from the company’s chief executive on allegations involving his ties to a Chinese businesswoman.
In a separate House track, Reuters reported that Foreign Affairs Committee Chairman Brian Mast and two senior Republicans asked Huang on November 4 to provide a closed-door briefing. The alleged briefing concerned Huang’s relationship with a Chinese businesswoman, according to the report; it did not establish that the request concerned counterintelligence memos. A spokesman for Mast said he was open to issuing a congressional subpoena if Huang did not respond to the request. Reuters reported that John Moolenaar gave Huang until 5 p.m. Eastern time on Wednesday, November 11, to decide whether he would meet lawmakers behind closed doors. The documented House track therefore remained a request for a briefing, with the possibility of resorting to subpoena power if Huang did not respond.
Lawmakers’ concerns relate to whether export controls and other safeguards can prevent Beijing from benefiting from sensitive U.S. technology. Reuters said Washington has spent years trying to restrict China’s access to advanced AI chips on national security grounds. Nvidia chips are widely used to train and run advanced AI models, placing the company at the center of U.S.-China competition in the field. Reuters quoted lawmakers as questioning whether the restrictions and safeguards are sufficient “to prevent sensitive U.S. technology from benefiting Beijing.” Under this framing, scrutiny is focused on how the chips reach China and the effectiveness of the controls, not on proving the espionage allegations cited in coverage.
Warren and Coons’ letter referred to Megaspeed and a possible investigation into the diversion of chips to China. The letter said, citing reports, that Megaspeed had bought more than $4.8 billion worth of Nvidia’s advanced AI chips since June 2024. It added that the Justice Department is investigating, according to the reports, whether the company diverted advanced chips to China in violation of U.S. export controls. The letter framed the matter as a possibility under investigation and did not present it as a confirmed violation. The senators linked their request to preserve records to the need to document matters related to the exports and potential national security risks.
In a separate development, Nvidia shares fell 5.3% by 10:30 a.m. Eastern time on Thursday, November 12, according to the Associated Press. The decline followed the company’s announcement that Huang had resigned as chief executive, the report said. The published report does not directly link the share-price move to the House request or the senators’ letter, so the stock decline and Huang’s resignation remain separate market context from the two oversight tracks. The available facts did not include a comparison with the stock’s performance in a previous session or market estimates. They also did not specify another figure for the stock’s move after the cited time.
On next steps in the House, the Foreign Affairs Committee said talks with Huang’s team about his testimony continued after his resignation and that it could use subpoena power if needed. The Associated Press reported that Huang had expressed willingness to take part in the interview, while the report did not set a new date for it. As for Warren and Coons’ letter, the deadline is November 17 for written confirmation that records-preservation instructions have been issued. The letter also requests a briefing for Congress on potential national security risks associated with chip exports. These deadlines and requests remain the procedural developments announced in the available facts.
