Raleigh, N.C. — The Wake County Board of Commissioners reviewed an audit Monday of all county departments for the past year and the Environmental Services Department for the past two years to determine if there was any questionable spending.

The audit came in response to Craig Wittig's June 3 firing from the county's Solid Waste Management Division after an internal review raised questions about travel expenses for 46 trips since he was hired in 2006.

Wittig has said that each trip to Disney World and Las Vegas and one trip that included whale-watching on the coast of Maine were to research environmental programs in other parts of the country so that Wake County could develop a state-of-the art recycling program.

County Manager David Cooke said Wittig's work-related expenses from April 2006 to April 2008 totaled $37,350.46. The county considers more than $19,000 of that amount questionable and nearly $10,000 recoverable, he said.

According to the audit, abusing tax dollars with out-of-town trips is not a systemic problem in Wake County.
