A House committee says a high-ranking Obama official misled lawmakers over the amount of Obamacare grants returned to taxpayers.

The House Energy and Commerce Committee issued a new report Tuesday that charged Andy Slavitt, acting administrator of the Centers for Medicare and Medicaid Services, with misleading lawmakers during a December hearing over a question on grants extended to state-run Obamacare exchanges. The administration stands by the testimony and says that the figure it originally reported was accurate.
