The Port Authority official who directed the shutdown of lanes to the George Washington Bridge said that he informed Gov. Chris Christie of New Jersey about it at a Sept. 11 memorial ceremony while the lanes were closed, according to an internal review that lawyers for the governor released on Thursday.

The official, David Wildstein, who was a longtime political ally of the governor, told Mr. Christie’s press secretary, Michael Drewniak, of the conversation at a dinner in December, on the eve of his resignation from the Port Authority of New York and New Jersey, according to the inquiry.

But the report said that Mr. Christie did not recall Mr. Wildstein’s raising the topic during their interaction and, in a sweeping claim of vindication, found no evidence that he — or any current members of his staff — was involved in or aware of the scheme before it snarled traffic for thousands of commuters in Fort Lee, N.J., from Sept. 9 to the morning of Sept. 12.

The inquiry instead blamed, almost entirely, Mr. Wildstein and the governor’s deputy chief of staff, Bridget Anne Kelly, for the scandal, describing Ms. Kelly as scrambling to cover up her role.
