US Commerce Secretary Howard Lutnick is set to answer Senate questions on December 10 about how the US handles NVIDIA's chip exports, especially with national security worries in play.
Sen. Tim Scott called for this hearing, saying it's crucial to keep a close eye on where advanced tech ends up.
Megaspeed International suspected Chinese intelligence ties
The hearing will also dig into Megaspeed International, a Singapore-based company suspected of ties to Chinese intelligence and possibly getting NVIDIA chips into China illegally.
Some critics think the Commerce Department should have blocked Megaspeed from US tech sooner.
Lutnick himself faces extra scrutiny over his links with Chinese entities, while NVIDIA CEO Jensen Huang has been asked to testify too, possibly under subpoena if he skips out.
