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.

"We might have to put DOGE on Elon," Trump told reporters on Tuesday morning, referring to the Department of Government Efficiency, which Musk spearheaded at the White House until May, tasked with cutting fraud and waste in federal spending.

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.
