US President Donald Trump threatened to look into deporting Elon Musk and cut off the billions of dollars in subsidies that Musk's companies receive from the federal government while talking to reporters at the White House on Tuesday.

Trump said he will "take a look" at whether the U.S. will deport Elon Musk, as the feud between the two continued.

Elon Musk, the world’s richest man, threatened to fund primary challenges against supporters of President Trump's sprawling tax and spendng bill 'if it is the last thing I do on this Earth.'
