House Speaker Paul Ryan (R-Wis.) and two House committee chairmen on Thursday unveiled the outline of the House Republican plan to replace ObamaCare. The plan includes tax credits for buying insurance, which would increase with a person’s age but do not change based on income, and incentives for people to open savings accounts to pay for medical expenses. The outline did not mention the cost, or how many people would gain insurance. The Affordable Care Act has extended coverage to 20 million people. The new plan also calls for sharply reducing payments to the 31 states that expanded Medicaid.
