Wisconsin Republicans Derrick Van Orden and Ron Johnson are pushing back on Elon Musk's vow to form a new "America Party" and unseat Republicans.

Donald Trump dismissed Elon Musk's newly launched "America Party" as "ridiculous," reaffirming his belief in the traditional two-party system. Trump's remarks followed Musk's unveiling of the party, intended to challenge the perceived "one-party system" in the United States.

The world's richest man's latest political activities prompted a brutal sell-off of Tesla stock as investors question his focus on the company.

The billionaire continued to criticize the GOP and appeared to take shots at the president after he mocked the idea of Musk creating a third-party in the U.S.
