Treasury OIG follow-up with Oklahoma County to request that Oklahoma County management performs an assessment over the $1,288,109 in grants funds paid to the Oklahoma County Home Finance Authority, which were not tested by Castro, to determine if rental assistance payments and prepaid debit cards payments were made utilizing solely Oklahoma County's CRF proceeds, or if these expenses were paid with State of Oklahoma and Oklahoma City funding sources. If support is not provided, Treasury OIG should recoup the funds or request Oklahoma County management to provide support for replacement expenses, not previously charged, that were eligible during the CRF period of performance.
