[US Congress Demands Huang and Lutnick Testify Regarding Chip Exports to China] According to Decrypt, Senate Banking Committee Chairman Tim Scott sent letters to former Nvidia CEO Jensen Huang and Commerce Secretary Tim Lutnick, requesting that they appear at hearings on December 3 and December 10, respectively. The letter stated that if Huang fails to attend, the committee will consider issuing subpoenas. Lutnick has agreed to attend. The chairpersons of three House committees also requested that Huang and Nvidia General Counsel Tim Teter be questioned behind closed doors on December 1 and 2. The investigation focuses on chip export controls to China and Nvidia's Singaporean customer, Megaspeed. US officials have identified a former Megaspeed executive as an intelligence operative, but the Department of Justice says no conclusion has been reached. Nvidia maintains that it complies with US export laws.
