Former Gov. Mike Easley said Saturday he isn't worried about the FBI reviewing records involving private air travel by him and his family and is sure the investigation will show he did nothing wrong.

"I am comfortable with the federal authorities collecting and reviewing all records relating to my 30 years of public service to the people of North Carolina," Easley said in an e-mailed statement to reporters. "I am confident of the outcome and we look forward to moving on with our private lives."

The statement said any questions should be referred to Easley campaign attorney John Wallace, who didn't return a message from The Associated Press on Saturday.

The FBI issued subpoenas Friday to the state Highway Patrol seeking information about trips taken by Easley and his family on privately owned aircraft.

The subpoenas are part of an ongoing grand jury investigation, according to the documents. The specific nature of the probe isn't clear.

But recent media reports about Easley, a two-term Democratic governor and now a partner in a law firm in Raleigh, have raised new questions about his activities while chief executive.

The State Board of Elections is reviewing loaner cars given to Easley and his family from dealerships that led the former governor to amend several years of campaign finance reports last month.

The board is also reviewing Easley's air travel. The News & Observer of Raleigh reported last week that Easley, while in office, flew on at least 25 private jets provided by several businessmen. He didn't pay for some flights, and the value of other trips appears to exceed campaign donation limits, which would be against the law, the newspaper reported.

McQueen Campbell, who was appointed to the N.C. State University trustee board by Easley and later became chairman, told the newspaper he provided many campaign flights for Easley and one for a Florida fishing trip. Campbell resigned Friday amid the flap over the hiring of Easley's wife, Mary, for a university job.
