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.'

Musk has taken issue with the bill saying that it flies in the face of everything he thought he was supporting. Trump appointed Musk to head up the newly formed Department of Government Efficiency and was tasked with reducing “waste, fraud, and abuse” in government spending.
