NEW: Nvidia CEO Jensen Huang admits to cheating on his wife two days after a report dropped that U.S. intelligence believes he had a relationship with a Chinese spy. "I was unfaithful to my wife," Huang said in a letter to Nvidia staff. "My actions hurt her and our children. There is no excuse for what I did." "I love our country and our company, and I am committed to protecting Nvidia and supporting America's national security," he said. The company has launched an independent investigation into Huang to determine whether he was the "target of a foreign intelligence effort." The woman in question, alleged Chinese spy Alice Huang, is suspected of smuggling chips to China. Photos show her with the Nvidia CEO, and she is accused of funneling information to Beijing.
