Elon Musk has sharply criticized President Trump’s flagship legislation, labeling it a “disgusting abomination” just four days after concluding his role as the chief cost-cutter at the White House.

Musk took aim at Trump’s “one big, beautiful bill,” which encompasses many of the president’s commitments, describing it as “pork-filled” and reinforcing his split from the administration.

According to the non-partisan Congressional Budget Office, the bill is predicted to increase the national debt by $3.8 trillion, although the White House contends it will stimulate growth and lead to future savings.

“I’m sorry, but I just can’t stand it any more,” Musk expressed. On Friday, he was presented with a golden key by Trump, commemorating his contributions to the Department of Government Efficiency, where he claimed to have achieved $175 billion in savings.

Musk elaborated on his views via X, his social media platform, stating, “This massive, outrageous, pork-filled congressional spending bill is a disgusting abomination. Shame on those who voted for it: you know you did wrong. You know it.”

Karoline Leavitt, Trump’s press secretary, dismissed Musk’s remarks during a briefing, stating, “Look, the president is aware of Elon Musk’s stance on this bill. It doesn’t change the president’s opinion. This is one big, beautiful bill and he’s sticking with it.”

The bill, which narrowly passed the House last month, has ignited significant contention within the Senate, where divisions among Republicans are evident as they criticize its content and strive to amend it before a vote set for this month. This will initiate a negotiation process with the House to arrive at a final version that Trump aims to sign on or before July 4, the national holiday celebrating the Declaration of Independence.

Included in Trump’s signature legislation for a second term are various tax cuts he pledged during his campaign. Yet, in a typical Washington maneuver, the bill’s 1,038 pages are filled with spending initiatives, or “pork,” aimed at fulfilling other commitments.

The non-partisan Joint Committee on Taxation, which serves Congress, has projected that the tax cuts’ costs could add $5 trillion to the national debt. Extending the individual tax cuts from Trump’s 2017 legislation, set to conclude this year, is estimated to decrease revenue by over $2 trillion through 2034.

Another major expenditure includes a proposed nearly $150 billion increase for the Pentagon, covering pay raises and housing improvements, alongside several acquisitions such as $4.6 billion for a Virginia-class submarine and $5.4 billion for additional missile destroyer ships. Trump has indicated this will push defense spending past $1 trillion for the first time.

The legislation allocates $46.5 billion for border security initiatives like expanding the wall and river barriers along the Mexico border, as well as $4.1 billion for the hiring and training of more border enforcement personnel, plus $12 billion to assist border states with infrastructure and patrols.

Notably, the bill’s final page permits increased borrowing, proposing a $4 trillion hike to the federal debt ceiling. This provision faces strong opposition from Senator Rand Paul of Kentucky, who is under pressure from Trump to soften his stance.

Trump responded on his Truth Social platform, stating, “Rand votes NO on everything, but never has any practical or constructive ideas. His ideas are actually crazy (losers!). The people of Kentucky can’t stand him. This is a BIG GROWTH BILL!”

Senate Republican leader John Thune can afford to lose three votes and still pass the bill, yet others have voiced their discontent as well.

Senators Ron Johnson of Wisconsin and Rick Scott of Florida have advocated for steeper spending cuts.

Scott remarked, “Their [the House] bill would not pass in the Senate, and I think many of us would oppose it.”

Of the $1.9 trillion in cuts proposed, a $698 billion reduction in Medicaid funding, which aids low-income and disabled Americans, has sparked backlash from Senators Susan Collins of Maine, Lisa Murkowski of Alaska, and Josh Hawley of Missouri. Hawley criticized this as “morally wrong and politically suicidal.” A significant portion of the cuts is attributed to a new requirement for recipients to work or study at least 80 hours per month.

It appears unlikely that any Senate Democrats will support the bill, especially given that it overturns many essential incentives from President Biden’s 2022 Inflation Reduction Act that were designed to promote investment in cleaner energy sources.

These reductions are contained within a section of the bill beginning on page 879 titled “Make America Win Again,” under the subsection “Working families over elites.”

Biden’s proposal included tax incentives lasting ten years, whereas the House’s version of the “big, beautiful” bill terminates these incentives at the end of the year, affecting credits for electric vehicles, energy-efficient home improvements, and residential clean energy installations like solar panels and geothermal heat pumps.

Incentives encouraging nuclear energy production and the manufacturing of wind and solar components are expected to phase out by 2028.

Conversely, fossil fuel initiatives would gain numerous advantages, expediting approvals for new extraction projects and eliminating a tax on methane emissions, along with repealing various measures aimed at reducing air pollution.
