Musk, who had been a close ally of the president, announced on X Saturday that he would be forming the “America Party.” His decision was based on an X poll that he posted on July 4, where he asked users on the social media website if there should be an America Party.

Musk left his post as head of Trump's Department of Government Efficiency (DOGE) when his special government employee contract ended May 30. While it was initially said that he would continue on in an advisory role, his fierce criticism of Trump's "Big Beautiful Bill" made the departure seem much more final.
