Virginia Attorney General Ken Cuccinelli on Wednesday reversed his office’s position on legislation involving the use of union labor on the Dulles Metrorail project, telling lawmakers that they could cut off $150 million in state funding for the project if the board overseeing construction continues to encourage the use of union labor.

Cuccinelli’s announcement contradicts the declaration his office issued earlier this week when it told Virginia lawmakers they lacked the authority to set rules for the regional Metropolitan Washington Airports Authority.
