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.

Musk, who supported Trump's campaign and also served as an adviser to the White House, has criticized the tax and spending bill the president is pushing.

U.S. Senate Republicans passed President Donald Trump's massive tax-and-spending bill on Tuesday by the narrowest of margins, advancing a package that would slash taxes, reduce social safety net programs and boost military and immigration enforcement spending while adding $3.3 trillion to the national debt.
