BRIDGEWATER, N.J. (AP) — Elon Musk said he’s carrying out his threat to form a new political party after his fissure with President Donald Trump, announcing the America Party in response to the president’s sweeping tax cuts law.

The tech billionaire’s effort to create a new political party, called the America Party, comes amid a ramped-up feud with the president over his new domestic policy law.

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.
