Rhode Island is getting a warning from the federal government about a possible suspension in funding due to mismanagement of food stamps.  The U.S. Department of Agriculture said this week in a letter to the Rhode Island Department of Human Services that it continues to monitor Supplemental Nutrition Assistance Program concerns following the implementation of the state's integrated eligibility system in September 2016, better known as UHIP.  The agency says it has found the state's progress on the issue insufficient and is issuing a formal warning of a suspension of up to nearly a million dollars in federal funding for administrative costs of the food stamp program.  Rhode Island now has 30 days to respond with correctional actions or evidence of compliance.
