Knox County auditor releases purchasing card audit [1]

Knox County's auditor released the draft audit of county purchasing card use this morning in a surprising reversal of previously stated policy.
Auditors have said they wouldn't release the long-delayed report, which covers thousands of transactions on purchasing cards issued to county employees, until the county administration has had the opportunity to respond, but the News Sentinel received a copy at the auditor's office shortly after 9 a.m. and is reviewing the initial findings.

UPDATE: Copies of the audit report at the KNS [2] and WBIR [3], KNS report here [4], WBIR report here [5].

UPDATE: By way of KAG [6], WBIR has created a searchable database [7] of p-card charges.
