I don’t think we ever got the straight story on this ‘incident’ to begin with, and I doubt that we are getting it now.
It seemed to me that what Christie did is take advantage of something that was scheduled months in advance. You can’t just wave a magic wand and have construction crews show up.
IMO, there "is" more but this is something that has been going on longer than Chris Christie has been on the planet. The Port Authority of New York and New Jersey dates to 1921. The port is the #3 US port by traffic volume and the Port Authority controls literally mountains of money. That inspires attempts by nearly every politician in the area to try to grab a piece of it.
I've read that Jersey City (under Mayor Steven M. Fulop, one of the "rising stars" of the NJ 'rat party) deliberately screwed up traffic entering and leaving a Port Authority trucking terminal. Why? Rectangular pieces of green paper with pictures of dead presidents, Jersey City would like more of them, thank you!
This is corruption on a massive scale and it has spanned decades, involves both political parties and involves both the State of New Jersey and State of New York.
