CHARLOTTE, N.C. (AP) – Republican gubernatorial candidate Pat McCrory says a public records request by the North Carolina Democratic Party is a “fishing expedition.”

The Charlotte mayor said Friday the records request filed this week with the City of Charlotte will cost more than $100,000 and take up to 1,000 hours to complete.

The request filed Thursday by party officials seeks all correspondence between McCrory, the city manager and his staff and three companies – Bank of America, Duke Energy and US Airways.

Party spokeswoman Kerra Bolton says the requests were specific and says the public has the right to know if the mayor has used taxpayer dollars wisely. Bolton would not say why party officials were seeking the information.

The gubernatorial campaign of Democratic Lt. Gov. Beverly Perdue said it’s aware of the request.
