The Oregon attorney general sued Oracle America Inc. on Friday, charging that the technology giant committed what "amounts to a pattern of racketeering activity" that cost the state hundreds of millions of dollars during the faulty rollout of its troubled health insurance exchange. In a scathing, 126-page civil complaint, Oregon Atty. Gen. Ellen Rosenblum accused the company and several of its high-level executives of repeatedly lying to state officials, of failing to deliver on contracts and of filing an estimated $240 million in false claims after it was hired to build the Cover Oregon website.
