Asked if he thought it would be likely that the state legislature would expand Medicaid coverage after refusing to do so previously, Tillis said it might make sense once the state has better control of the financing of the program, which is notorious for its cost overruns.

He said he didn't have an ideological objection to expanding the coverage. But he said when the state auditor told the previous governor that money was being wasted on it, the appropriate response would not have been to make it bigger and more costly.

"I would encourage the state legislature and governor to consider it if they're completely convinced they now have the situation under control," Tillis said.
