>> reporter: good evening, brian, the appointee is david wildstein, it is important to note we don't know what the evidence is, the letter did not specify. also important to note his lawyer is trying to get his legal fees paid. but if this is substantiated you have to wonder how can chris christie survive this?

>> reporter: late this afternoon, a lawyer for david wildstein the former port authority official linked in the george washington lane closure scandal produced a letter disputing chris christie 's claim that he didn't know anything about it.
>> let me tell you, everybody, i was behilind sided.
>> reporter: in the letter, he says the governor not only knew but it was his order, the letter ties him to the lane closures during the period when the lanes were closed, contrary to what the governor stated publicly in a two-hour press conference.
>> this is a hugely significant development in the investigation. it is a direct challenge to the credibility of governor christie, but until we see the evidence that david wildstein is talking about it is very hard to know how to evaluate.
>> reporter: on january 9th in that press conference, christie strongly denied knowing about it, adding it was a political vendetta.
>> i am humiliated by the fact i didn't know it, i was deceived. it was an awful way to feel.
>> reporter: wildstein who had already resigned when he appeared before the assembly, would not answer any questions.

>> i don't know what documents he is referring to. we had subpoenaed documents from him. i'm a little frustrated as committee chair that we had asked for documents from him through a valid subpoena. he provided us over 900 pages. and apparently the documents he referred to were not part of that response.
>> reporter: and the voices are only going to get louder after this. forget presidential hopes, brian, many now say that if this is proved he should resign or be impeached.
