Conservative commentator: If Christie's involved in bridge scandal, he should 'resign now'

(CNN) - E-mails emerged on Wednesday from top aides to New Jersey Gov. Chris Christie bolstering suggestions that George Washington Bridge lane closures last year that tied up traffic stemmed from a political vendetta and not bureaucratic incompetence as his administration claimed.

Christie said in a statement that "what I've seen today is unacceptable," adding that he was "misled by a member of his staff" and knew nothing about what had transpired.

"I like Chris Christie, I hope that he wasn't involved, said co-host of CNN's "Crossfire" S.E. Cupp. "But if he was, and if he knows that he was and this will come out later ... if I were giving him advice (that I know he won't take): Resign now."
