New Jersey Bridgegate is not slowing down. Questions around how and why several George Washington Bridge access lanes were shut last September – around what Governor Chris Christie knew and when he knew it – are not only growing, they’ve now gone viral.Thanks to Jimmy Fallon, Bruce Springsteen and a devastating “Born to Run” update, the scandal has jumped from political fiasco to pop culture phenomenon. And like those cars in Fort Lee, the issues pile up: Who’s lying? Who’s telling the truth? Why was this done?
