On Saturday, Elon Musk launched a series of criticisms against a massive spending bill intended to fund much of President Donald Trump’s plans, attacking it again as Senate Republicans hasten to pass this “big, beautiful bill” before the July 4 deadline set by Trump.

“The latest Senate draft bill will devastate millions of American jobs and cause immense strategic damage to our nation!,” Musk posted on X. “Completely insane and destructive. It gives subsidies to outdated industries while severely harming future industries.”

The billionaire and former adviser to Trump highlighted a poll indicating the “big, beautiful bill” is politically unpopular due to its financial impact, a view confirmed by several separate polls this month. An NBC News Decision Desk poll found 40% of Republican respondents said “reducing the national debt” is the top priority as Congress reviews the Trump-backed mega bill. Overall, most respondents prioritized keeping current spending levels for programs like Medicaid.

“Polls show that this bill is political suicide for the Republican Party,” Musk wrote on X.

Musk has long been a critic of Trump’s “big, beautiful bill,” balking at its expected impact on the national deficit and arguing that it would offset government savings brought in by the Department of Government Efficiency, an organization Trump appointed him to lead earlier this year. He maintained that opinion Saturday, expressing it through several posts on his platform, X — including one post that attacked the bill’s expected effect on the deficit “as “putting America in the fast lane to debt slavery!”

Trump previously argued that Musk only opposed the legislation because of provisions aimed at stripping away electric vehicle tax credits. Musk today called a provision in the bill that he framed as targeting clean energy production “incredibly destructive to America.”

The Tesla chief’s departure from the White House, where he formally served as a special government employee, came a day after he publicly expressed his criticisms of the bill during an interview with “CBS Sunday Morning.”

“I think a bill can be big or it can be beautiful, I don’t know if it can be both,” Musk said at the time.

While Musk no longer commands similar levels of influence in Washington, his past opposition to the bill emboldened Republicans lawmakers, some of whom, like Musk, took issue with its expected $4 trillion increase to the national deficit.

The renewed criticism by Musk comes as Senate Republicans rush to whip enough votes to pass the 940-page megabill amid breaks in the party over certain provisions, including expected cuts to Medicaid that could strip funding from rural hospitals. Sen. Thom Tillis, R-N.C, cited the loss of rural hospital funding in explaining his decision to oppose the bill.

Earlier this month, shortly after the House of Representatives passed its version of the bill, Musk urged his more than 200 million followers on X to tell Congress to “kill the bill.”
