The truce between Elon Musk and President Donald Trump didn’t even last a month. After the Senate narrowly passed a procedural vote to debate Trump’s “Big, Beautiful Bill” over the weekend, Musk on Monday said he would use his vast resources to launch primary campaigns against Republicans in Congress who voted for the massive domestic policy agenda.

Musk has taken issue with the bill saying that it flies in the face of everything he thought he was supporting. Trump appointed Musk to head up the newly formed Department of Government Efficiency and was tasked with reducing “waste, fraud, and abuse” in government spending.
