“I am outraged and deeply saddened to learn that not only was I misled by a member of my staff, but this completely inappropriate and unsanctioned conduct was made without my knowledge,” Mr. Christie’s statement said. “One thing is clear: This type of behavior is unacceptable, and I will not tolerate it because the people of New Jersey deserve better. This behavior is not representative of me or my administration in any way, and people will be held responsible for their actions.”

His office did not respond to follow-up inquiries about whether this meant Ms. Kelly, or anyone else, had been fired. Mr. Wildstein, along with Bill Baroni, Mr. Christie’s top appointed staff member at the Port Authority, resigned in December after port officials testified in a legislative hearing that the men had violated protocols and had sought to hide their plans for the lane closings from Fort Lee officials, the police and even other Port Authority officials.

The documents were obtained by The New York Times and other news outlets Wednesday. They are heavily redacted by Mr. Wildstein, who turned them over under a subpoena from Democratic legislators investigating the lane closing, making it hard to determine in some cases who is speaking.

But they indicate that Mr. Christie’s staff, appointees at the Port Authority, and his campaign office were all intimately involved in discussing the growing scandal and how to react to it even as it was unfolding.

After New York appointees at the Port Authority, who had not been warned in advance about the closings, reopened the lanes four days after they were closed, Mr. Wildstein and Ms. Kelly expressed panic, but Mr. Wildstein assured her that David Samson, Mr. Christie’s handpicked chairman of the Port Authority, was “helping us to retaliate.”

When reporters began calling to ask about the lane closings, Mr. Wildstein and Ms. Kelly worked with Michael Drewniak, the governor’s chief spokesman, to fashion a statement saying that the port was “reviewing traffic safety patterns” at the bridge and had been “in contact with Fort Lee police throughout this transition.”
