On Monday, June 30, Musk vowed that if the Republican-controlled Congress passed Trump's "Big, Beautiful Bill" — which the Tesla CEO has repeatedly slammed — he would form and fund the "America Party" in an effort to oust GOP lawmakers.

Bannon said Musk ― a naturalized U.S. citizen ― “should be deported,” while Musk predicted that Bannon ― who served a four-month sentence for contempt of Congress ― could be heading back to prison for a longer term. Bannon on his “War Room” podcast slammed Musk for saying he would start a new political party, the America Party.

And Musk seemingly can’t let that go. “Physics sees through all lies perfectly,” Musk posted this week on his social-media platform X. The Tesla and SpaceX CEO’s political power in Washington—which just a few months ago seemed limitless —was always about proximity to the president.
