Twenty-two million more people would be without health insurance over the next decade under Senate Republicans' plan to repeal and replace Obamacare, according to an analysis released Monday by the nonpartisan Congressional Budget Office.

Senate Republicans unveiled a "discussion draft" of the bill Thursday of their plan to repeal and replace Obamacare that would end the health care law's penalties for people who don't buy insurance, cut back an expansion of Medicaid, but would keep more protections for people with pre-existing conditions, compared to a House-passed bill.
