President Donald Trump’s budget proposal, to be rolled out Tuesday, likely will include Medicaid reform. But with several approaches having been floated, definitive answers will have to wait until the White House releases the fiscal plan.

During his Senate confirmation hearings in January, Health and Human Services Secretary Tom Price said he would look at changes to Medicaid, the federal-state health insurance program for the poor.

Medicaid covers about 70 million low-income Americans. Thirty-one states and the District of Columbia expanded eligibility for Medicaid under Obamacare.

When serving as House Budget Committee chairman as a congressman from Georgia, Price advocated giving Medicaid funds to states in block grants as a way of providing more flexibility.
