Virginia Attorney General Mark Herring says the condition of public school buildings is the primary responsibility of localities and local school boards. Herring issued his opinion Friday in response to several questions raised by state Sen. Bill Stanley, R-Franklin, who has been leading a push to repair Virginia’s deteriorating schools, particularly in financially strapped rural and urban areas. Stanley and some colleagues in the Senate are expected to introduce a few bills related to school infrastructure to be considered when the General Assembly session starts Wednesday.
