President Donald Trump said on Sunday that billionaire Elon Musk's move to start a new U.S. political party is ridiculous and could add to confusion. "I think it's ridiculous to start a third party," Trump told reporters before boarding Air Force One in Morristown,

The US president was commentating for the first time on the billionaire’s plans to form a third party to challenge the Republicans and Democrats.

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.
