Payments to States

The Secretary shall from time to time certify to the Secretary of the Treasury for payment to each cooperating State the sums necessary to enable such State as agent of the United States to make payments provided for by this part. All money paid a State under this section shall be used solely for the purposes for which it is paid; and money so paid which is not used for such purposes shall be returned, at the time specified in the agreement under this subpart, to the Secretary of the Treasury. Any agreement under this subpart may require any officer or employee of the State certifying payments or disbursing funds under the agreement or otherwise participating in the performance of the agreement, to give a surety bond to the United States in such amount as the Secretary may deem necessary, and may provide for the payment of the cost of such bond from funds for carrying out the purposes of this part.
