Terry McAuliffe, the Democratic candidate for governor in Virginia, lashed out Friday at Republican Attorney General Ken Cuccinelli for threatening to use his office to block the historic transportation package that passed the General Assembly last month.

During a sitdown Thursday with Politico at the Conservative Political Action Conference, Cuccinelli hinted that he may yet issue a legal opinion that could derail the tax hike in the package that would raise the extra money the state needs. The measure is awaiting Gov. Bob McDonnell’s signature.
