Elon Musk’s feud with President Donald Trump — and seemingly any congressional Republicans who support the president’s massive tax cuts and spending package — has reignited, with the tech billionaire threatening to launch a new political party, and Trump suggesting Musk could be punished for his opposition.

Musk — who spent at least $250 million supporting Trump in the 2024 presidential campaign as the main contributor to America PAC — said in May that he would likely spend “a lot less” on politics in the future. But his recent statements seem to indicate he might be rethinking that stance.

On Monday, the tech billionaire and former Department of Government Efficiency chief lashed out multiple times at Republicans for backing Trump’s tax cuts bill, calling the GOP “the PORKY PIG PARTY!!” for including a provision that would raise the nation’s debt limit by $5 trillion and calling the bill “political suicide” for Republicans.

After a post pledging to work toward supporting primary challengers for members of Congress who backed the bill, Musk responded “I will” to a post in which former Michigan Rep. Justin Amash asked for Musk’s support of Rep. Thomas Massie. Trump and his aides are already targeting the Kentucky Republican for voting against the measure, launching a new super PAC devoted to defeating him.

Tuesday morning, Musk replied “You’re awesome” to an X post from Massie recirculating news coverage of Musk’s support of him.

Musk is the chief executive of Tesla, the nation’s largest electric vehicle manufacturer, and SpaceX, which has massive defense contracts.

Overnight, Trump posted on social media that Musk has long known of his opposition “against the EV Mandate,” which he called “ridiculous.” Saying that, without subsidies, the Tesla CEO “would probably have to close up shop and head back home to South Africa,” Trump suggested that “Perhaps we should have DOGE take a good, hard, look at this? BIG MONEY TO BE SAVED!!!”

Several times, Musk has suggested that a new political party is needed to encapsulate the viewpoints he argues aren’t represented by the GOP.

On Monday afternoon, Musk suggested that the “America Party” would be formed if “this insane spending bill passes,” saying the U.S. “needs an alternative to the Democrat-Republican uniparty so that the people actually have a VOICE.”
