Trump admin live updates: Trump says Musk will 'pay the consequences' if he funds Democrats

The "One Big Beautiful Bill Act" could add $2.4 trillion to the deficit over the next decade, according to the nonpartisan Congressional Budget Office.

The CBO released new estimates on the legislation on Wednesday as focus turns to the Senate, where a handful of Republican members are expressing concerns about the deficit and changes to Medicaid.

The budget office is projecting 10.9 million more people will be uninsured in 2034 because of changes to health care.

Speaker Mike Johnson told reporters Wednesday morning that he had nothing but respect and praise for Elon Musk for his work "reducing waste, fraud and abuse," and said he has talked to Musk about his criticisms of the big, beautiful bill.

"We've laughed about our difference on policy before," he said. "I'm not upset about this."

Johnson however said Musk was "flat wrong" about his criticisms on the spending bill and its effect on the deficit. The speaker said that Trump was also upset with Musk's scathing appraisal of the bill,

"He's not delighted that Elon did a 180 on that," Johnson said of Trump.

Johson said he called Musk last night, but he didn't answer.

"I hope to talk to him today," Johnson said.

House Majority Leader Steve Scalise criticized the nonpartisan Congressional Budget Office's report that said the spending bill would add to the national deficit.

Scalise claimed that the report did not "recognize the economic growth" that would reportedly come with cuts to spending and other changes.

"I get we have to play by the rules of the referee, but the referee is wrong. The referee is trying to sack our quarterback," he said.

Prior to the nonpartisan Congressional Budget Office's report on Trump's spending bill, one of its staunchest supporters sounded off in an X post Wednesday for its passage.

White House deputy chief of staff Stephen Miller claimed that the extension of the 2017 tax rates "has zero deficit impact which is why the bill, because of its spending cuts, reduces the deficit."

The argument comes as the CBO and other experts project that it will add to the deficit.

Miller called out Sen. Rand Paul by name after Paul vocally criticized the fact that the bill does not reduce the deficit. Miller said that libertarians like Paul are "attacking the tax cut."
