Great reporting, and tenacity, by Maddow and her staff who all refuse to let go of the bull's tail. The killer here is that the George Washington Bridge is Federal property and, therefore, subject to direct oversight, the Port Authority of NY & NJ having only supervision and management.
This means that no amount of political intervention from either the NY or NJ State governments can prevent criminal investigation by US Justice.
Will Holder mess with a Republican governor who bro-hugged Obama post-Sandy? Stay tuned.
