Another high-ranking state official has resigned in connection with the federal and state investigations of former Governor Mike Easley. Laura Leslie of North Carolina Public Radio reports. Cameron McRae is the latest Easley ally to step down from his post. The former governor appointed McRae to the powerful state Board of Transportation. An investigation into Easley's campaign records found that McRae was one of several people who gave Easley free air travel without reporting it as a campaign donation. Easley didn't report the flights, either. Bob Hall with Democracy NC says the former governor should've known better. "If people are paying expenses - they're holding fundraising parties for you - that's a campaign expense and it has to be disclosed. Same thing if you're giving them a flight to the campaign event." A federal grand jury is hearing testimony today on another facet of the investigation - former first lady Mary Easley's job at NC State. Another friend who gave the governor free air travel was McQueen Campbell, chairman of the school's board of trustees. He resigned from that position last week.
