US lawmakers to probe Trump administration's Nvidia chip exports to China

The US Senate Finance Committee and the House Ways and Means Committee are set to launch an investigation into the Trump administration's decision to approve exports of Nvidia chips to China, according to a letter from lawmakers.

Separately, Nvidia co-founder and chief executive Jensen Huang resigned with immediate effect. Chief Financial Officer Colette Kress has taken over as interim CEO, while the company's board has initiated a search for a permanent successor. US President Donald Trump has also suggested former Apple CEO Tim Cook as a possible replacement for Huang.

Nvidia has previously denied wrongdoing in connection with allegations surrounding its business dealings. The company has also said it has no reason to believe that its trade secrets or US national security have been compromised.
