The "One Big Beautiful Bill Act" -- a massive tax and immigration bill to fund much of President Donald Trump's agenda -- will 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.

The White House preemptively defended the bill just before the CBO release, with deputy chief of staff Stephen Miller accusing the nonpartisan office of being "lefty" and touting the legislation as a "dream bill."
