Two bills making their way through Missouri's Republican-led Legislature represent the state's latest attempt to oppose the federal health care law. Senators passed measures last week that would impose additional regulations on insurance navigators, who help consumers sign up for health plans on the exchange marketplace. One bill would require navigators to take a written exam and undergo a criminal background check before working with consumers. Another would require navigators to purchase a $100,000 bond and be liable for unlawfully sharing a customer's personal or financial information. Republicans say the measures would protect Missourians from fraud.
