The US Congress threatened the head of Nvidia with a subpoena for not appearing at the “briefing”

Republicans in the U.S. House of Representatives are threatening to issue a subpoena to Nvidia CEO Jensen Huang if he does not agree to come to a closed-door briefing before Wednesday.

The reason was the publication about his relationship with an employee of the Singapore company Megaspeed Alice Huang, which American intelligence agencies believe recruited by the Ministry of state security of China.

The initiator was the Chairman of the Committee on foreign Affairs Brian Mast, said that he had accumulated a “long” list of questions to the businessman. He said he was "100%" concerned about national security risks. “These are American chips ... We don’t want China to have access to them, he told ABC News.

Last week, Must, along with Rick Crawford, chairman of the House Intelligence Committee, and John Moulenar, chairman of the House China Committee, sent Huang a letter asking him to appear at a "joint briefing behind closed doors.".

Jensen Huang himself has not yet responded to a Republican request for a briefing. In January, the Republicans will lose control of the committees, so the subpoena issued now may lose force, and the Democrats will have to issue a new one.

US President Donald Trump told reporters that he had a phone conversation with Huang, and he allegedly “had no idea” that his girlfriend could be a spy. Chinese authorities, in turn, called the accusations “baseless slander.”.

The head of Nvidia in an appeal to employees admitted to treason. He apologized to his wife and children, but did not name the woman he was in a relationship with. Huang has been married to Lori Huang since 1985 and the couple have two children.
