Republicans are using Congress’s official budget scorer as a whipping boy, as they argue a major package of President Trump’s tax priorities is costless, despite multiple projections placing the plan’s price tag at trillions of dollars over the next decade.

While the Congressional Budget Office (CBO) has not yet released its final estimate of House Republicans’ “One Big Beautiful Bill Act” as it advances on Capitol Hill, Republicans have increased attacks on the nonpartisan office over its cost projections of the party’s tax cuts plan — which seeks to permanently lock in expiring provisions in Trump’s 2017 tax plan, along with a host of other add-ons.
