WHITE: The Trump coalition is beginning to fracture, and in a lot of ways, there is historical precedent for this. Trump and Grover Cleveland have a lot in common besides serving non-contiguous terms as president.

U S President Donald Trump has hit out at former close ally Elon Musk over the multi-billionaire's plan to launch a new political party. "I am saddened to watch Elon Musk go completely 'off the rails,' essentially becoming a train wreck over the past five weeks," Trump posted on his Truth Social platform on Sunday.

Musk left his post as head of Trump's Department of Government Efficiency (DOGE) when his special government employee contract ended May 30. While it was initially said that he would continue on in an advisory role, his fierce criticism of Trump's "Big Beautiful Bill" made the departure seem much more final.
