US lawmakers have expanded their investigation into Nvidia, demanding testimony from the company’s former CEO and senior government officials. The probe, initially focused on chip exports to China-linked firms, now includes calls for former CEO Jensen Huang to appear before Congress. The inquiry follows revelations that Huang was in a relationship with a businesswoman suspected of ties to Chinese intelligence.

The Senate Banking Committee, led by Chairman Tim Scott, has joined House committee chairmen in requesting Huang’s testimony. The lawmakers are examining potential national security risks and White House oversight of advanced chip exports. The investigation also includes former Commerce Secretary Howard Lutnick, who has agreed to testify over Nvidia’s chip exports and the role of Singapore-based firm Megaspeed.

The scandal has raised concerns about U.S. Technology competitiveness and the implications for artificial intelligence. Reports of Huang’s resignation and his alleged ties to Chinese espionage have led to fears of reduced U.S. Influence in the global tech sector. Meanwhile, China has expressed skepticism about U.S. Restrictions, vowing to continue its own technological development.

The situation highlights growing tensions between the U.S. And China over technology exports and national security. The probe underscores the political fallout from the scandal, with Trump’s Cabinet facing internal questions over decisions involving Nvidia. As the investigation unfolds, the outcome could shape future U.S. Policies on tech exports and international relations.
