Trump has been warned that Nvidia CEO Jensen Huang was romantically involved with a suspected Chinese spy before allowing him to join a May trip to Beijing, despite his claim that he knew nothing about it.
Secretary of State Marco Rubio reportedly briefed Trump aboard Air Force One, but the president dismissed concerns and allowed Huang to join.
US intelligence has reportedly identified Alice Huang as a Chinese spy.
Jensen Huang initially denied the affair but later admitted it, prompting Nvidia to open an investigation.
Trump continues to defend Huang, calling him a "very honorable man," but says the executive will not accompany him on his next visit to China.
