Medicaid has grown in size in recent years, with ObamaCare extending coverage to millions of low-income people who hadn’t qualified before. But Republicans warn of the program’s growing costs and have pushed to provide that money to states in the form of block grants — an idea President-elect Donald Trump endorsed during the campaign.

Vice President-elect Mike Pence signaled in an interview with ABC this month that the incoming administration planned to keep Medicare as it is, while looking at ways to change Medicaid.

“I think President-elect Trump made it very clear in the course of the campaign that, as president, we’re going to keep our promises in Social Security and Medicare,” Pence told ABC. “With regard to Medicaid, though, I will tell you, there’s a real opportunity, there’s a real opportunity as we repeal and replace ObamaCare to do exactly what the president-elect also said on the campaign, and that is block granting Medicaid back to the states.”
