Elon Musk’s feud with President Donald Trump has reignited, with the tech billionaire threatening to launch a new political party and Trump suggesting Musk could be punished for his opposition.

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.'

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.
