FILE - This Feb. 13, 2014 file photo shows U.S. Rep Greg Walden, R-Ore., announcing a request form U.S. House Republicans for the U.S. Government Accountability Office to investigate how $304 million in federal grants was spent on the troubled Cover Oregon online enrollment system for the federal health insurance overhaul. With him is state Rep. Dennis Richardson, who is running for governor. Due to similar requests from several members of Congress and committees, the GAO agreed Wednesday, March 5, 2014 to look into problems with state health exchange websites around the country. The agency says which states will be determined as the investigation goes forward. (AP Photo/Mail Tribune, Bob Pennell)
