Congress summons ex-Nvidia CEO Jensen Huang over national security concerns

Former Nvidia CEO Jensen Huang has been summoned to testify before multiple US congressional committees over national security concerns tied to his company's dealings with Singapore-based MegaSpeed, with lawmakers threatening subpoenas if he fails to appear. The closed-door interviews, scheduled for December 1 and 2, involve Huang and Nvidia's General Counsel Tim Teter, addressing AI chip smuggling, potential interference in US export control investigations, and adversary military use of Nvidia products. Committee chairmen Mast, Moolenaar, and Crawford stated there are "clear national security concerns that need to be addressed immediately." Huang has indicated willingness to attend, though the tone marks a shift from earlier correspondence. He also faces a public Senate Banking Committee hearing on December 3, while Commerce Secretary Howard Lutnick has accepted a separate invitation. The investigations follow reports linking MegaSpeed to China's access to high-performance GPUs and Huang's prior association with suspected spy Alice Huang.
