Treasury OIG follow-up with Mississippi's management to confirm if the $1,324,066 noted as unsupported expenditures within the Direct Payments greater than or equal to $50,000 and Aggregate Payments to Individuals payment types can be supported. If support is not provided, Treasury OIG should recoup the funds or request Mississippi management to provide support for replacement expenses, not previously charged, that were eligible during the CRF period of performance. Further, based on Mississippi's responsiveness to Treasury OIG's requests and its ability to provide sufficient documentation and/or replace unsupported transactions charged to CRF with valid expenditures, Castro recommends Treasury OIG determine the feasibility of conducting an audit for the Direct Payments greater than or equal to $50,000 and Aggregate Payments to Individuals payment types.
