Former Nvidia chief executive Jensen Huang is due to testify before the United States Congress following his admission of an affair with a woman accused of links to Chinese intelligence.
The technology giant has said that no company data was compromised and that there were no breaches of national security. The FBI and Department of Justice have nevertheless launched investigations.
The case has raised questions over whether the allegations could damage the US chip-manufacturing industry and how Washington will respond to potential spying at senior levels of one of the world’s most valuable companies.
Huang, described as a technology superstar, resigned as chief executive before his expected appearance before Congress.
The affair and the alleged intelligence links are at the centre of scrutiny, while the investigations examine whether any sensitive information was accessed or national security was affected.
