Donald Trump has unleashed on former MAGA mate Elon Musk, accusing him of being a “train wreck” and “off the rails” in a searing Truth Social post. The latest spat between the president and the richest man in the world has flared up after Musk officially fied paperwork to start his new “America Party”.

President Donald Trump said he was "saddened to watch Elon Musk go completely 'off the rails'" in recent weeks.

"When it comes to bankrupting our country with waste & graft, we live in a one-party system, not a democracy," Musk said in the announcement.
