Trump said Monday that he has cut a deal with chipmaker Nvidia, allowing it to sell certain artificial intelligence chips to China in exchange for a cut of the revenue, which would go to the U.S. government. Trump said he also negotiated a similar deal with chipmaker Advanced Micro Devices (AMD).

Why Nvidia’s and AMD’s China deal with Trump could backfire. The companies making the most money from the AI boom are the ones selling the processors, such as Nvidia and AMD.

One dismayed Democratic lawmaker said the move signals to China “that American national security principles are negotiable for the right fee."
