The US Senate Banking Committee wants former NVIDIA CEO Jensen Huang and Commerce Secretary Howard Lutnick to answer questions about possible Chinese spying.
Lawmakers are especially focused on how NVIDIA handles tech exports to China and on Huang's connection to Alice Huang, who is being investigated for allegedly spying for China.
NVIDIA China business under scrutiny
NVIDIA is facing tough questions about its business with China as the US tries to protect its tech secrets.
The committee also wants answers from Lutnick, who has been slow to blacklist some Chinese companies.
So far, neither Huang nor Lutnick has commented publicly, but the Senate says they're serious about getting answers, even hinting at a subpoena if needed.
