More than a month after their initial social media bluster, Elon Musk has announced the formation of a new U.S. political party in response to U.S. President Donald Trump signing his sweeping tax and spending bill into law.

Elon Musk said he's carrying out his threat to form a new political party after his fissure with President Trump, announcing on social media that he would form the America Party in response to the president's sweeping new law.

Treasury Secretary Scott Bessent criticized Elon Musk 's new political party, saying the world's wealthiest man wasn't a popular part of the Trump administration. Asked about Musk's move, Bessent told CNN's Dana Bash that the ideas behind the administration's Department of Government Efficiency effort, also known as DOGE, were "very popular."
