Musk previously threatened to start the new "America Party" last week, expressing his disapproval of Trump's "One Big Beautiful Bill Act" and declaring that he would form a new political party if it passed. This spending bill ultimately did pass, with Trump signing it into law on Friday, July 4.

WASHINGTON, July 5 (Reuters) - The dispute between Republican President Donald Trump and his main campaign financier Elon Musk took another fractious turn on Saturday when the space and automotive billionaire announced the formation of a new political party, saying Trump's "big, beautiful" tax bill would bankrupt America.

Billionaire Elon Musk said Saturday he is forming a third political party, after a dramatic falling out with Donald Trump, indicating he will make good on threats he made if the president’s domestic policy bill became law.
