This week, Trump has said Musk would have to "close up shop and head back home to South Africa" if he halted government subsidies to his companies, and then later added that his administration would "have to take a look" at deporting Musk.

Elon may get more subsidy than any human being in history, by far, and without subsidies, Elon would probably have to close up shop and head back home to South Africa,” Trump said.

President Donald Trump said he will 'have to take a look' at deporting Elon Musk to his native South Africa as their fight reached new heights.
