Political and legal pressures are tightening on New Jersey Gov. Chris Christie following a former aide’s claim Christie knew of the George Washington Bridge closing scandal last September.

Over the weekend, Christie and his aides denied the claim by David Wildman, a Christie appointee to the Port Authority of a New York and New Jersey. Wildman released his claim of evidence via an attorney in an attempt to win immunity from prosecution.

Wildman is shown at right along with former Deputy Chief of Staff Bridget Anne Kelly. Christie has called his fired staff “stupid” and “callous” as the governor blamed them for the four-day closing of two access ramps in Fort Lee, NJ. The closings created a massive tie-up in the borough and on the bridge, which connects New Jersey and Upper Manhattan.

Christie has argued that he was too busy to know about the ramp closing, ostensibly for a “traffic study” that staffers have yet to produce.

Christie’s stance has prompted the parody at left modeled on the Hogan’s Heroes TV character Sgt. Schultz and his saying, “I know nothing!”

New York Times reporter Kate Zernicke wrote a story Jan. 31 headlined, Christie Knew About Bridge Lane Closings. She reported that Wildstein, a high school friend of Christie’s, said it was “the Christie administration’s order” to close the lanes. She reported also that Wildstein alleges “evidence exists, as well, tying Mr. Christie to having knowledge of the lane closures, during the period when the lanes were closed, contrary to what the governor stated publicly in a two-hour press conference” three weeks ago.

Update: On Feb. 10, the Washington Post reported the kind of scandal we have been sharing here for more than four years in, Chris Christie’s long record of pushing boundaries, sparking controversy.

Meanwhile, Harvard Law School professor and political pundit Alan Dershowitz told the conservative site Newsmax,“The Dominoes Are Beginning to Fall’ for Christie.” In an interview with reporter Todd Beamon, Dershowitz said Christie needlessly insulted Wildman at a Dec. 13 news conference.

“Gov. Christie really made his stupid mistake by treating Wildstein the way he did,” Dershowitz said. “He provoked him. Christie showed his total ineptness when he said what he said about Wildstein at the press conference.”

For years, the Justice Integrity Project has reported on Christie’s abuse of office. In such columns as, Christie’s Corruption Case Shows Horrid Legacy of ‘Loyal Bushies,’ Cover-ups, we have revealed his methods of using his post as New Jersey’s U.S. attorney to reward his friends, punish his enemies, and launch his successful gubernatorial campaign in 2009.
