DECATUR, Ga. (AP) — DeKalb County's CEO says he is halting taxpayer-funded charge cards for government officials.

The Atlanta Journal-Constitution (http://bit.ly/1FM7tEp) reports that Interim CEO Lee May says outside investigators handling a review of local corruption recommended the change. County commissioners, their staff and most of the county's 300 employees who have the cards are affected.

May says that investigators Mike Bowers and Richard Hyde found improper expenses, including unauthorized transactions and card holders who split purchases to get around the county's $1,000 cap per transaction.

The cards still could be used for emergencies, motor vehicle repairs or court expenses.

The newspaper reports that a recent audit of spending on the cards found the DeKalb Board of Commissioners spent more than $250,000 since 2006 but submitted receipts for only 57 percent of the expenses.
