Elon Musk is going public with his true feelings about President Trump’s One Big Beautiful Bill Act, calling it an “abomination” and shaming every House member who voted for it. 

Mr. Musk has tepidly been raising questions about the bill in recent weeks, and then finally went public with a screed against the legislation in an X post on Tuesday. 

“I’m sorry, but I just can’t stand it anymore,” Mr. Musk writes. “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,” he added. 

The White House was unconcerned by Mr. Musk’s post, which was sent out as Press Secretary Karoline Leavitt was briefing reporters on Tuesday. 

“The president already knows where Elon Musk stood on this bill. It doesn’t change the president’s opinion. This is one big beautiful bill,” she said when asked about the post. 

The majority leader, Senator Thune, was in the middle of preparing for his weekly press conference when Mr. Musk sent out his post. Mr. Thune brushed off the billionaire’s concerns, saying that he was relying on a deficit score that underestimates economic growth, which he says will help close the deficit. 

“We obviously respect everything Elon did with DOGE,” Mr. Thune said. “We have a difference of opinion. He’s entitled to that opinion.”

The White House later sent out a list of 50 bullet points, seemingly in response to Mr. Musk and other critics, that highlighted the “wins” in Republicans’ One Big Beautiful Bill Act. The list included provisions from the House-passed bill that make the 2017 tax reforms permanent, cutting taxes on tips and overtime, and phasing out green energy tax credits. 

“Here are 50 reasons why President Donald J. Trump’s One Big Beautiful Bill is the best chance in a generation to pass critical reforms for which Americans voted,” the White House wrote in their press release just 90 minutes after Mr. Musk’s original post. 

A small band of Republican senators have said they need to see major changes to the bill because of the deficit implications. A new study from the Joint Committee on Taxation — Congress’s in-house scorekeeper — says the bill may add as much as $3.7 trillion to the deficit over ten years. 

Over the weekend, Mr. Musk said in an interview with CBS News that he was “disappointed” that Republicans would back such a proposal. 

“I was disappointed to see the massive spending bill, frankly, which increases the budget deficit, not just decreases it, and undermines the work that the DOGE team is doing,” he said. 

Republican senators were questioned on Monday and Tuesday this week about the deficit implications of the bill. The Senate had been on recess all of last week after the House passed the legislation with just two GOP members voting no. 

As of Tuesday, there appears to be enough senators to sink the legislation if it were to come to the floor as written. Senator Johnson and Senator Lee says their party is spending far too much on the bill. Senator Paul says he does not want to vote to raise the debt limit, which is included in the package. Senator Hawley is opposed to the current Medicaid reforms that were passed by the House. 

After Mr. Musk made his denunciation on Tuesday, Mr. Lee responded with an X post of his own. 

“These numbers are nothing short of stunning,” Mr. Lee said of the One Big Beautiful Bill Act. “Congress has hollowed out America’s middle class through reckless deficit spending and the inflation it causes.”
