According to Deltaone, citing US Senator Kevin Cramer's remarks on CNBC, Cramer is willing to support a congressional subpoena if NVIDIA CEO Jensen Huang refuses to testify. Cramer also called for Huang's resignation and expressed support for tightening export controls on AI chips. He stated that Congress may investigate NVIDIA's chip exports to China and Commerce Secretary Lutnick's handling of the restrictions. This is a statement by the lawmaker; the original text does not state that a subpoena has been issued or an investigation has been launched.
