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.'

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.
