States that experienced severe technical problems in running their ObamaCare exchanges would have to reimburse the federal government for the cost under a Republican bill introduced Wednesday. "This bill rightly restores accountability by ensuring that the hundreds of millions of dollars wasted by these failed exchanges are returned," said Sen. Orrin Hatch, the top Republican on the Senate Finance Committee. The repayment rule would specifically apply to states that hand control of their marketplaces to the Department of Health and Human Services, as Oregon will do before ObamaCare's second enrollment period begins in November.
