Nvidia's co-founder and former CEO Jensen Huang resigned from the company amid allegations that he was involved in a relationship with a businesswoman suspected of working for Chinese intelligence. The news emerged as U.S. Lawmakers intensified their investigation into potential national security risks related to advanced chip exports to China.

Republican House committee chairmen and Senate Banking Committee chairman Tim Scott sent letters demanding testimony from Huang. The probe follows reports that Huang had a relationship with a businesswoman linked to Chinese intelligence. The situation has raised concerns about the oversight of technology exports and the role of company executives in national security matters.

Huang's sudden resignation has caused a rift within the technology industry. A letter circulating online claimed that top NVIDIA leadership wanted him reinstated, but NVIDIA VP Bryan Catanzaro confirmed he did not sign it. The letter also included names like chief AI scientist Bill Dally. The letter is now considered fake.

Huang played a central role in Nvidia's rise, overseeing 60 direct reports and lacking a clear succession plan. His departure has left the company in a state of uncertainty. Reports suggest that Nvidia considered appointing Arm CEO Rene Haas as his successor.

Huang's career, which began as a refugee from war, has now been overshadowed by the scandal. The incident highlights the growing scrutiny on tech leaders and their potential ties to foreign governments. The situation continues to unfold as the company navigates the fallout.
