US President Donald Trump has said that Nvidia CEO Jensen Huang told him he had "no idea" that the woman he had an affair with was an alleged Chinese spy. This was reported by Qazaqyia.kz citing BBC News.

Speaking to reporters, Trump said he spoke with Huang on Monday following reports that the US believed he had been targeted in a Chinese espionage campaign. "I asked him that question, 'Did you have any idea she was a spy?' He said 'I had no idea she was a spy' and I really believe him," Trump said.

According to a New York Times report, US intelligence officials believe Alice Huang, also known as Huang Le, was a spy for Beijing.

China has rejected claims that Huang was targeted, with its foreign ministry saying the allegations were "entirely groundless, speculative and intended to smear and malign China".

Nvidia, which commissioned an independent investigation into the affair involving Alice Huang, said it had no reason to believe the company's secrets or national security were compromised.

Trump also said the FBI was investigating the affair but did not elaborate on the probe or when it was launched.
