The resignation and allegations
Huang, who founded Nvidia in 1993 and had served as CEO since then, admitted on Sunday to having been "unfaithful" to his wife after reports he had an extramarital affair with a suspected Chinese spy, Alice Huang. Alice Huang (no relation) worked as an executive at the Singaporean firm Megaspeed. She has been suspected of being an intelligence asset for China, according to the New York Times. China has rejected those allegations as a smear.
US Attorney General Todd Blanche said on Thursday the Department of Justice had not yet drawn any conclusions about whether Alice Huang was engaged in espionage for Beijing.
According to US media, Huang's alleged second affair was with a long-time Nvidia executive, Kimberly Powell, who reported directly to him within the company. Sources have told the BBC that Nvidia employees had noticed the pair were unusually close.
Nvidia announced it had launched an investigation into whether its CEO had been "the target of a foreign intelligence effort". The company has said it has "no reason to believe that either national security or Nvidia secrets were compromised", but pledged that its independent inquiry would look at all available information.
