Musk Vows to Back GOP Primary Challengers Over Megabill Support

Elon Musk has vocally opposed President Donald Trump's "big beautiful bill," a major economic package that extends tax cuts, increases defense spending, and reduces Medicaid funding, primarily due to its projected trillions in added national debt. Musk warned that any member of Congress who campaigned on reducing government spending but then supports this bill should "hang their head in shame" and pledged to back primary challengers against such lawmakers in the next election cycle. He also proposed forming a new political entity called the "America Party" as an alternative to the traditional two-party system if the bill passes. Despite previously supporting Trump’s efforts to streamline government spending, Musk's relationship with the president has soured, partly due to policy disagreements and leadership picks. The Senate continues to debate the bill, with most Republicans backing it under pressure from President Trump, who has criticized holdouts. Musk's threat to challenge lawmakers marks a potential return to active political engagement after a period of stepping back.
