United Kingdom, July 7 -- President Donald Trump has branded Elon Musk a "train wreck".

The 78-year-old commander-in-chief hit out at his former friend and advisor after the tech mogul declared his intention to start his own political party, the America Party, and warned the Space X boss that the initiative would fail.

He wrote on his Truth Social platform: "I am saddened to watch Elon Musk go completely 'off the rails,' essentially becoming a TRAIN WRECK over the past five weeks. He even wants to start a Third Political Party, despite the fact that they have never succeeded in the United States."

Trump warned that Musk's plans for a third political party to rival the Democrats and Republicans would cause "total disruption and chaos"....
