A public feud between President Donald Trump and his on-again, off-again ally, billionaire Elon Musk, reignited this week after an apparent truce lasted less than a month.

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.

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.
