Trump calls Nvidia chief Jensen Huang an 'honorable guy' amid spy allegations

US President Donald Trump has defended Nvidia CEO Jensen Huang following reports of his links to a woman suspected of spying for China.

Trump praised Huang and said he had not spoken to him about the allegations. "I have not spoken to him about it. I just know he's a fine person, you never know what's going on. I'm sure, I hope everything's fine. He's done such an incredible job, so I would certainly hope that, he's a fine person, in my opinion."

Asked whether he regretted not acting on intelligence about the alleged relationship earlier, Trump replied: "I think he's an honorable guy. I think he probably has an excuse for it."

Huang, who leads one of the world's most valuable technology companies, acknowledged to Nvidia's board that he had been unfaithful to his wife with a business executive suspected by US intelligence of gathering information for Beijing.
