The Federal Bureau of Investigation has opened a preliminary investigation into Oregon's state-based exchange to determine why Cover Oregon failed to function, preventing it from signing up any consumers online, reported The Oregonian. The FBI also is reportedly looking into allegations that Cover Oregon officials showed the federal government a misleading website demonstration so they could continue receiving federal funds. The FBI's investigation follows several other audits of the Cover Oregon marketplace, including the U.S. Department of Health & Human Services Inspector General, the Government Accountability Office and the U.S. House Oversight committee. But it's still unclear how vigorously all the agencies are pursuing their investigations. The Oregonian reported neither state nor Cover Oregon officials have been contacted about the investigations. After being plagued with technical problems, Cover Oregon became the first state to completely replace its exchange with the federal version. Article
