NVIDIA-PROBE-CONGRESS:House Republicans push for Nvidia's Huang to testify, float subpoena over spy allegations A trio of House Republicans are unlikely to allow Nvidia CEO Jensen Huang to send his company's general counsel to answer questions on his behalf about his alleged relationship with aChinese spy, according to a person familiar with the discussions. House Foreign Affairs Chairman Brian Mast and two other top Republican lawmakers asked Jensen Huang to provide a closed-door briefing. (via REUTERS)House Foreign Affairs Chairman Brian Mast and two other top Republican lawmakers on November 4 asked Huang to provide a closed-door briefing about a New York Times report alleging he had a close relationship with a Chinese businesswoman who passed information to Beijing. Mast is open to issuing a congressional subpoena if Huang doesn’t respond to their request, his spokesperson said. Lawmakers need support from colleagues to issue a subpoena, and the rules to do so vary by committee. Deep DiveThe US and China are locked in a race to develop increasingly powerful AI systems, with Nvidia at the center because its advanced chips are widely used to train and run cutting-edge models. Washington has spent years trying to restrict China's access to those chips on national security grounds, and the allegations involving Huang have intensified lawmakers' concerns about whether export controls and other safeguards are strong enough to prevent sensitive US technology from benefiting Beijing.

A spokesperson for Nvidia did not immediately respond to a request for comment.
