A former New Jersey official is claiming Gov. Chris Christie knew about the closures of traffic lanes leading to the George Washington Bridge when they occurred. The official, David Wildstein, helped coordinate the closures with a top Christie aide when he worked at the Port Authority last year. Christie has denied having any knowledge, saying he only found out when the scandal broke open last month. But in a new statement, Wildstein says “evidence exists” Christie was aware at the time, contrary to his public statements. Wildstein is seeking legal immunity as well as Port Authority backing for his attorneys’ fees in the probes surrounding the case. In a statement, the Christie administration denied Wildstein’s claims, saying he is only “looking for the Port Authority to pay his legal bills.” The Christie administration faces a deadline of today to comply with a subpoena for handing over documents to a state legislative investigation.
