"Now that Nvidia CEO JENSEN HUANG, who has done a fantastic job, has resigned, there is only one man to take his place -- TIM COOK of Apple," Trump said on his Truth Social network.

Trump has no formal say in who should run chip giant Nvidia, which is at the center of the AI revolution, but his extraordinary intervention underscores his close ties to both Huang and Cook.
