Elon Musk's social media fight with President Trump over the budget bill this week threatens to have a larger impact.

President Donald Trump and Elon Musk are trading public insults after the Tesla billionaire suggested he'll create a new political party, "America Party."

Trump has tools at his disposal—from stripping citizenship to invoking the Defence Production Act to nationalise Musk’s empire. One has money, the other has raw political power. In the end, Musk must remember: you can’t launch rockets into politics without expecting blowback.
