Democratic senators Elizabeth Warren and Chris Coons urged the administration of US President Donald Trump to preserve all documents related to Nvidia’s chip exports to China in a letter addressed to Commerce Secretary Howard Lutnick, Secretary of State Marco Rubio and White House Chief of Staff Stephen Miller, The Guardian reported.
In their letter, the senators said, “This incident raises serious concerns about the federal government’s ability to effectively enforce export controls and protect our national security.”

A relationship raises security concerns
The crisis began when Huang admitted on Sunday, in a message to company employees, that he had cheated on his wife, stressing that there was “no excuse” for what he had done. US media outlets say the relationship was with Alice Huang, an executive at Singapore-based Megaspeed, one of Nvidia’s major customers, whom US intelligence believes works for Chinese intelligence agencies. Beijing rejected the allegation, while Huang denies knowing of any ties between her and the Chinese government.
Nvidia’s board launched an independent investigation into the national security concerns and assigned it to the law firm Wachtell, Lipton, Rosen & Katz. Taiwan’s immigration authorities canceled Alice Huang’s entry permit to the island, according to the BBC.
Board meets as shares plunge
The Wall Street Journal, citing people familiar with the matter, reported that Nvidia’s board was preparing to dismiss Huang, who co-founded the company in 1993. CNBC confirmed that the board meeting continued into Wednesday evening. The company’s shares fell by more than 8 percent in after-hours trading.

Several US lawmakers, including Republican Senator Kevin Cramer, had called on Huang to resign, while Trump expressed his support for him and described him as “an honest man.” Nvidia, which makes the chips used to train artificial intelligence models, is at the center of the technological race between the United States and China.
