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.

President Donald Trump and Elon Musk are trading public insults after the Tesla billionaire suggested he'll create a new political party, "America Party."

Elon Musk has said that he’s formed a new political party, but it’s unclear what steps — if any — he’s taken to do so, or how the effort might affect upcoming elections. Musk has not yet released any additional information. Spokespeople for Musk and his political action committee, America PAC, didn’t immediately comment Monday.
