Andy Slavitt — President Obama’s choice to manage Obamacare, Medicare and Medicaid — was linked seven years ago to a massive medical data fraud scheme that resulted in what was then the largest settlement ever by an insurance company.

If he is confirmed by the Senate, Slavitt will head the Centers for Medicare and Medicaid, which manages the federal government’s three biggest health care programs. He will manage an estimated $1 trillion in benefits that are paid to millions of doctors, patients and hospitals.
