Detroit Emergency Manager Kevyn Orr ordered an investigation into the city’s employee-benefit programs, including the insurance and pension systems, Bloomberg News reported yesterday. Orr told the city’s inspector and auditor general, agencies that both have subpoena power, to report within 60 days in an order dated yesterday. The document should cover “next steps, and any corrective, prospective, legal, additional investigatory or other action designed to address any waste, abuse, fraud or corruption uncovered,” according to Orr’s order.
