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.'

Joe Gebbia, a confidant of the technology billionaire and a Tesla director, is also a leader of the federal cost-cutting team. The fight might put him in a bind.
