US Commerce Secretary Howard Lutnick received a highly classified intelligence memo warning of NVIDIA CEO Jensen Huang's relationship with Alice Huang, who US intelligence officials suspect worked for Chinese intelligence, according to Axios.
The memo, prepared under the supervision of Secretary of State Marco Rubio, was aided by surveillance of Alice Huang and an investigation into alleged chip smuggling involving her company, MegaSpeed, which purchased billions of dollars worth of NVIDIA chips.
Rubio also warned President Trump directly before his visit to China in May.
