U.S. President Donald Trump lashed out against Elon Musk after he formed a new political party, calling the move “ridiculous,” and saying the tech billionaire had gone “completely off the rails.”

Axar.az informs “I am saddened to watch Elon Musk go completely ‘off the rails,’ essentially becoming a TRAIN WRECK over the past five weeks,” Trump said in a post on Truth Social late Sunday stateside. “The one thing Third Parties are good for is the creation of complete and total disruption and chaos.”

Musk said in a post on X Saturday that he had set up the “American Party” to compete against the Republican and Democratic parties. The billionaire had teased for weeks the idea of a new political party, taking on Trump over the tax and spending plans that he said would bankrupt the economy.

“By a factor of 2 to 1, you want a new political party and you shall have it!” Musk wrote, “Today, the America Party is formed to give you back your freedom.”

“I think it’s ridiculous to start a third party. We have a tremendous success with the Republican Party. The Democrats have lost their way, but it’s always been a two-party system, and I think starting a third party just adds to confusion,” Trump said Sunday, Reuters reported, a day after Musk’s announcement.
