Nvidia launched an investigation into CEO Jensen Huang after he admitted to having a close relationship with a woman identified by US intelligence agencies as a Chinese spy.
Alice Huang is an executive at MegaSpeed, a major Nvidia customer suspected of "helping China gain access to limited-use artificial intelligence chips," The Washington Post reports.
Huang apologized to his wife for the betrayal, and Navidia said there was no evidence that trade secrets or national security had been compromised.
He will remain CEO for the duration of the investigation.
