On paper, David Wildstein's title at the Port Authority of New York and New Jersey was "Director of Interstate Capital Projects." But many who worked there knew his real job, a post created just for him in 2010, was to further Republican Gov. Chris Christie's agenda inside the agency.He led efforts to give New Jersey officials more sway over authority operations. And he was seen as having unsurpassed connections to Christie's inner circle. Now, the man who was known as the administration's eyes and ears at the Port Authority may be the public's best chance of knowing the truth behind a plan last summer to purposely create days of traffic gridlock in Fort Lee, N.J., by choking off local access to the George Washington Bridge.
