TLDR: Apparently last fall a few aides for Chris Christie (New Jersey governor) closed access lanes to the George Washington Bridge in Fort Lee after the mayor didn't endorse Christie's reelection, and now some email's have surfaced that show these aides communicating the plan / execution of it. Christie claims not to know anything of it, and still insists it was due to an incompetent traffic study even despite these emails.
Christie is my favorite Republican, but he has often come off and somewhat hard-handed. This, however, would cross a serious line if he were involved.
