A legislative committee is proposing a cut in the fees to fund Rhode Island's health insurance exchange.  The House Finance Committee made a slight cut to Governor Gina Raimondo's plan to assess a fee to keep HealthSource RI open for business.  The exchange is operated by the state to provide a marketplace for insurance coverage under the Affordable Care Act.  Rhode Island is one of only 14 states that run their own exchange, with the rest using the federal system.
