In the wake of the Supreme Court’s ruling upholding the federal health law, Missouri Governor Jay Nixon is not taking a clear stance on whether he thinks the state should take part in a voluntary expansion of its Medicaid program. The health law originally required states to raise Medicaid eligibility to about 130 percent of the federal poverty level. But the Supreme Court ruling now leaves that decision up to states. Speaking to reporters in Kansas City Monday, Nixon said he hopes to work with providers, businesses, and lawmakers to figure out what’s best for Missouri.
