US Secretary of State Marco Rubio sent a secret memo to the presidential administration in the spring of 2026, warning of ties between Nvidia CEO Jensen Huang and a Chinese citizen suspected of espionage, the New York Times writes. According to intelligence reports, the woman worked for the Ministry of State Security of the People's Republic of China and served as a senior manager of Singapore's MegaSpeed, which purchased $2 billion worth of Nvidia AI chips for illegal supply to China. In the past, due to contacts with this company, the US Congress initiated an investigation into Huang.
