Weeks after Elon Musk said he would step back from politics, he's back in the fray publicly bashing the Republican megabill and calling for the formation of a new party if the bill passes.

The billionaire and former Trump adviser suggested that if the domestic policy bill passed, he would swiftly form a new “America Party” and back primary challenges to Republicans.

Billionaire Elon Musk said on Monday that he would form a new political party in the United States if a Republican-leaning Congress passes President Donald Trump’s “One Big Beautiful Bill”, which proposes tax breaks and funding cuts for healthcare and food programmes.
