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.

In a late-night post on social media, Trump hit back against Musk and threatened to direct the Department of Government Efficiency (DOGE) against the tech billionaire.

In a post on Truth Social, Trump took aim at Musk for the subsidies his companies have received, particularly for electric vehicles. Trump said without them, Musk would "probably have to close up shop and head back home to South Africa." Trump had also said "we'll have to look" when asked if he would consider deporting Musk.
