The Congressional Budget Office (CBO) projected Monday that the last-ditch GOP ObamaCare repeal bill would result in "millions" of people losing coverage.

The agency did not give a specific number given a lack of time to do the analysis before a vote, but said the "direction of the effect is clear."

CBO said the reduction in coverage would be felt in three areas: in Medicaid, because the bill repeals ObamaCare's expansion of Medicaid; in private coverage, because the bill repeals subsidies that help people afford it; and because the mandate to have coverage would be repealed.
