Donald Trump has lashed out at Elon Musk after the billionaire unveiled plans to launch a new US political party, calling him a “train wreck” in an escalation of the feud between the US president and his former ally.

Trump has since admitted he is 'very disappointed' by Musk's outburst, claiming that the X owner was 'wearing thin' in his DOGE role and was 'asked' 'to leave', and threatened to deport the South African out of the United States.
