President Donald Trump said the U.S. intelligence bureau ( FBI) is conducting an investigation into the romantic relationship Nvidia’s CEO Jensen Huang had with a suspected Chinese spy, Alice Huang. 

Nvidia’s CEO and Ms Huang have the same surname but are not related.

The investigation would determine whether Mr Huang ,63, exposed the U.S. technology used in making cutting-edge data chips to China, which it views as its main rival in the competition for AI dominance.

“I know the FBI is looking into it in terms of something else, and I think that he’ll be in good shape,” Mr Trump said on Monday at a White House briefing.

The U.S. leader said he spoke directly to Mr Huang who claimed innocence, that he wasn’t aware his ex-girlfriend was spying on Nvidia for China.

“I did speak to him today just to see if he’s feeling all right, how you’re doing,” Mr Trump said. “He said he had absolutely no idea that the person in question was a spy.”

Mr Huang admitted he cheated on his wife with Ms Huang who is also known as Huang Le, in an apology message he sent to company staff.

He has been married for about 40 years to Lori Huang, an electrical engineer whom he met in Oregon State University. The couple have two children, Madison and Spencer who are also employed in Nvidia.

Nvidia, which previously denied Mr Huang’s affair with the Chinese woman following an article by The New York Times, released another statement on Sunday announcing investigation into the matter after its CEO’s confession.

“I support the investigation and will cooperate fully. I love our country and our company. I am committed to protecting NVIDIA and supporting America’s national security,” Mr Huang wrote in his letter.

Nvidia’s shares slumped 4.3 per cent, losing about $230 billion in value following reports and investigation of the affair.

U.S. Congress members, Senator Mark Warner and House Representative Hakeem Jeffries have also shown interest in the matter and demanded a full briefing.

“We’re going to need a full briefing, specifically as it relates to the Nvidia issue, so we can all get to the bottom of what has happened,” Mr Jeffries said, “and what the implications are in terms of America’s national security.”

Ms Huang was a top executive at MegaSpeed, a South Asian firm, that buys chips used in powering data centres. The company has purchased $4.6 billion worth of chips from Nvidia since June 2024.

As U.S. and China compete for superiority in the AI revolution, Washington banned sales of sensitive data chips to Beijing.

The U.S. government investigated and surveilled Ms Huang to determine whether she was helping China evade U.S. restrictions and move Nvidia chips to China, through her relationship with Mr Huang.
