Some lawmakers in D.C., including an Indiana senator, believe Nvidia is too close with China.

NVIDIA CEO Jensen Huang said that more chip plants are set to be in the United States, but the major chip maker will also continue its longstanding China-based operations with their planned R&D facility based in Shanghai.

That caught the attention of Indiana Senator Jim Banks, “No American company should be helping the Chinese Communist Party ‘close the AI gap,'” Banks said in a letter written to Huang. “NVIDIA was built by American innovation and taxpayer-funded research, not by empowering our adversaries.”
