Just hours after officially stepping down as the head of the Department of Government Efficiency (DOGE), Elon Musk made it clear he wasn’t going quietly. In a blistering Tuesday afternoon post on X, Musk condemned President Trump’s flagship spending bill — dubbed the “big, beautiful bill” — calling it a “disgusting abomination” and a betrayal of fiscal restraint.

I’m sorry, but I just can’t stand it anymore.

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.

Musk’s criticism wasn’t new, but the timing made waves. Over the past two months, as the bill made its way through Congress, Musk had increasingly expressed discomfort with its growing size and scope. In mid-May, he described the bill’s bloated allocations as “deeply disappointing” in a CBS interview, arguing it undercut the very mission of his agency. That mission — to root out waste and slash bureaucratic excess — had been Trump’s idea, and Musk’s role was once hailed as the keystone of a leaner government.

Despite their early alignment, the split became public weeks ago. As the House prepared to pass the bill before Memorial Day, Musk privately lobbied for sharper cuts and publicly warned of “a tidal wave of pork.” The bill ultimately passed the House with zero Democratic support and just two GOP defections — a fact Trump later used to rally his base.

Now, in his first day as a private citizen again, Musk’s words hit harder: “Shame on those who voted for it,” he posted Tuesday. “You know you did wrong. You know it.”

The White House, meanwhile, brushed off the criticism. Press Secretary Karoline Leavitt told reporters Trump remains “proud” of the bill and “grateful” for Musk’s past service — but added, “This is a big, beautiful bill, and the president’s sticking to it.”

Trump himself has remained diplomatically vague on the rift. When asked about Musk’s concerns last month, he pivoted to the votes: “We needed the support. We got it. It’s not perfect, but it’s progress.”

Yet behind the scenes, the divide has unsettled parts of the GOP. Some lawmakers — like Sen. Rand Paul — echoed Musk’s complaints, warning that the bill doesn’t do enough to cap the debt or rein in spending. Others, frustrated with Musk’s public outbursts, have said the billionaire’s role should have ended sooner.

Still, Musk’s departure — and his final critique — might not be the end of the story. He and Trump are slated to appear together at a press conference later this week. Whether they’ll present a united front, or double down on their differences, is anyone’s guess.

But one thing’s certain: the man who came to Washington to trim the fat just took a torch to the final product.
