Governor Pat Quinn has signed a bill expanding the state's Medicaid program. The expansion will cover low-income Illinois adults who don't have children at home. It's a big part of President Obama's health care law. Quinn says it'll give many Illinois residents access to quality health care. The governor says he wanted to sign it into law before Obama visits his home state later this week.
Up to half a million uninsured will be newly eligible for coverage. The federal government will foot the bill the first three years.
Some Republicans say they're worried about being able to sustain the expansion.
