Republicans in the U.S. Senate on Thursday unveiled a bill that would dramatically transform the nation’s Medicaid program, make significant changes to the federal health law’s tax credits that help lower-income people buy insurance and allow states to water down changes to some of the law’s coverage guarantees.

The bill also repeals the tax mechanism that funded the Affordable Care Act’s benefits, resulting in hundreds of billions of dollars in tax cuts for the wealthy and health care industry.
