In the interest of protecting the state bond ratings, State Treasurer Dale R. Folwell, CPA, today called for N.C. Department of Transportation Secretary J. Eric Boyette to replace the department’s chief operating and financial officers. Treasurer Folwell previously called for Gov. Roy Cooper to replace former NCDOT Secretary James Trogdon and to transfer financial management of NCDOT to the Office of State Budget and Management because of the gross financial mismanagement of NCDOT.
