Last week, Sen. Grassley (R-IA) and House Energy and Commerce Committee Chairman Upton (R-MI) sent a letter to HHS Secretary Sebelius claiming "inadequate or non-existent" oversight of more than $1 billion that has been distributed to establish American Health Benefit Exchanges. Citing reports of questionable use of funds by states, the lawmakers asked the Secretary to report on the effectiveness of efforts the Department may be taking to monitor uses of funds, as well as measures it's taking to combat possible fraud and abuse.
