US President Donald Trump has said that the FBI is investigating an affair between the head of Nvidia and an alleged Chinese spy. Trump said that on Monday he had spoken to Nvidia CEO Jensen Huang. Earlier there were reports that America believed that China had targeted Huang as part of an espionage campaign. Trump told reporters, "I asked him if he knew that woman was a spy? He said I had no idea she was a spy at all. And I really believe him." China has rejected these allegations. China's Foreign Ministry said that these allegations are completely baseless, based on speculation and have been made with the intention of tarnishing China's image. Nvidia has launched an independent investigation into this matter related to Alice Huang. Alice Huang is accused of being a Chinese spy. The company said that it has no reason to believe that company secrets or information related to national security has been compromised.
