North Carolina’s elected state treasurer wants two top state Department of Transportation executives replaced following recent reports of overspending and salary raises at the agency. Republican Dale Folwell said Wednesday that DOT Secretary Eric Boyette should remove the chief operating officer and chief financial officer because the agency's “continued mismanagement” threatens the state’s top-notch ratings when issuing debt. The department has been subject of two negative audits since May and two bailouts by the legislature since last fall. The department had no comment on Folwell's demand. DOT is a Cabinet agency for Democratic Gov. Roy Cooper.
