The Senate Republican health care bill would insure 22 million fewer people after a decade than current law, according to an analysis Monday by the non-partisan Congressional Budget Office. Fifteen million more people would be uninsured next year alone.

The GOP bill, titled the Better Care Reconciliation Act, would save $321 billion in the same period by spending $1 trillion less on health care and using the savings to repeal the Affordable Care Act’s taxes, which primarily benefit wealthy individuals and medical companies.
