WASHINGTON, July 1 — Elon Musk has intensified his opposition to a sweeping tax-cut and spending package backed by U.S. President Donald Trump, accusing lawmakers who supported the bill of betrayal and vowing political retaliation.
Calling the legislation “utterly insane and destructive,” the Tesla and SpaceX CEO took to social media platform X over the weekend and again on Monday, escalating his public criticism after weeks of silence.
“Lawmakers who campaigned on cutting spending but backed this bill should hang their heads in shame!” Musk wrote. “And they will lose their primary next year if it is the last thing I do on this Earth.”
The remarks come as the Senate deliberates the massive bill, which Musk argues will balloon the national debt and undo the cost-saving measures he claims to have achieved through the Department of Government Efficiency (DOGE), a controversial federal initiative he once led during the Trump administration.
Musk’s latest comments have further strained his relationship with Trump. Despite having poured nearly $300 million into Trump’s re-election efforts and playing a central role in shaping DOGE, Musk now accuses both parties of fiscal irresponsibility.
“We live in a one-party country — the PORKY PIG PARTY!!” Musk posted Monday. “Time for a new political party that actually cares about the people.”
Though Musk’s influence in Washington remains uncertain, his outbursts are fueling concern among Republican leaders, who worry that the billionaire’s break from Trump could jeopardize their grip on Congress in the 2026 midterm elections.
Privately, some GOP operatives say Musk’s deep pockets and social media reach could become a disruptive force if he follows through on threats to target incumbents in primary races.
The political turbulence has had financial consequences as well. Shares of Tesla experienced sharp swings amid the ongoing drama, temporarily wiping out around $150 billion in market value before rebounding in recent days.
As of now, the future of the legislation remains unclear, but Musk’s re-entry into the debate has added new volatility — both in Washington and on Wall Street.
