Ex-Trump ally billionaire Elon Musk’s latest promise could throw a major wrench into Trump’s governance plans for his second term.
Musk once more sounding off against the president’s signature budget bill currently making its way through Congress.
‘If this insane spending bill passes, the America Party will be formed the next day,’ Musk pledged in a post on X Monday evening.
‘Our country needs an alternative to the Democrat-Republican uniparty so that the people actually have a Voice,’ he added.
A couple of hours before announcing his intention to challenge fellow Republicans in primary elections, Musk criticized their failure to approve bills that meet his standards of conservatism in a post on X on a Monday afternoon. This happened while senators were voting on different amendments to Trump’s budget proposal.
The full Senate is expected to vote on the budget bill either late Monday night or early Tuesday morning, following President Trump’s urging for Congress to have it ready for his signature by July 4th.
The Senate version of Trump’s bill is estimated to add between 3.3 billion and 4.5 billion to the national debt.
‘It is clear, with the excessive spending outlined in this bill, which raises the debt ceiling by a historic Five Trillion Dollars, that we essentially have a one-party system in this country – the Porky Pig Party!!’ Musk expressed on X.
‘Time for a new political party that actually cares about the people,’ Musk added.
A few minutes later, Musk also called out several House Republicans who are a part of the conservative ‘Freedom Caucus,’ for their votes to pass the House version of the bill.
‘How can you call yourself the Freedom Caucus if you vote for a Debt Slavery bill with the biggest debt ceiling increase in history? @RepAndyHarrisMD @chiproytx,’ Musk wrote, addressing the two GOP lawmakers directly.
Musk then escalated his attacks further, pledging to oust Republicans from Congress who vote for the bill.
He said that any GOP lawmakers who ‘campaigned on reducing government spending and then immediately voted for the biggest debt increase in history’ while adding they ‘should hang their head in shame!’

Tesla CEO Elon Musk speaks alongside U.S. President Donald Trump to reporters in the Oval Office of the White House on May 30, 2025 in Washington, DC. Musk, who served as an adviser to Trump and led the Department of Government Efficiency, announced he would leave his role in the Trump administration to refocus on his businesses.
Musk, the world’s richest man now worth over $400 billion, founded the AmericaPAC super pac in 2024.
AmericaPAC raised over $260 million last year, and spent it in support of Republicans, many of whom ran in swing districts. Over $88 million went to directly supporting Trump.
Musk was rewarded handsomely for his efforts, and spent nearly four months in Trump’s White House as a ‘special government employee’ leading the Department of Government efficiency (DOGE).
In that role, he pinpointed many areas where the federal government could make budget cuts, but in Musk’s eyes much of that work will be for nothing if the government doesn’t curb its record high spending levels.
Some libertarian-minded Republicans have previously taken Musk’s side in the GOP budget fight.
New additions to the the national debt were have been a non-starter for the likes of Kentucky Republican Rand Paul, who notes that he does want to see the 2017 tax cuts made permanent.
Paul also described the current $5 trillion in new debt that the budget bill would add as ‘Biden spending levels.’
‘This will be the largest increase in the debt ceiling ever in our history. We’ve never raised the debt ceiling without meeting the target. You can say it doesn’t directly add to the debt but if you reach the ceiling you’ll meet that. We won’t discuss it for a year or two. I think it is a terrible idea to do this’ Paul told Fox News earlier in June.
Paul has also contrasted the pending package with the funds anticipated to be saved by spending cuts pushed for by DOGE.
‘That’s more than all the DOGE cuts that we found so far. So, the increase in spending put into this bill exceeds the DOGE cuts. When you look just at the border wall, they have $46.5 billion for the border wall,’ Paul said on Face the Nation earlier this month.
Utah GOP Senator Mike Lee is another Senate Republican who hasn’t fully supported President Donald Trump’s ‘big, beautiful bill’ of a spending package which is currently being voted on in the U.S. Senate after being passed by the House of Representatives back in May.
Lee and Musk previously joined forces to describe the bill as ‘debt slavery’ in a back and forth exchange on X.
