On Friday evening, the governor’s office issued a statement reacting to the letter.

“Mr. Wildstein’s lawyer confirms what the Governor has said all along – he had absolutely no prior knowledge of the lane closures before they happened and whatever Mr. Wildstein’s motivations were for closing them to begin with. As the Governor said in a December 13th press conference, he only first learned lanes were closed when it was reported by the press and as he said in his January 9th press conference, had no indication that this was anything other than a traffic study until he read otherwise the morning of January 8th,” the statement said.

Christie also appeared Friday evening at Howard Stern’s 60th birthday celebration at the Hammerstein Ballroom in Midtown, where he introduced Jon Bon Jovi before a musical performance, cracked a few jokes, and talked about Super Bowl XLVIII.

Christie did not address the bridge scandal at the event, and rushed past Sloan and other reporters as he left despite being mobbed by cameras. He smiled and waved, but answered no questions, as he got into a car and left.

The governor has maintained that he knew nothing of the lane closures until a state legislative panel began investigating.

“I had no knowledge or involvement in this issue in its planning or its execution and I am stunned by the abject stupidity that was shown here, regardless of what the facts ultimately uncovered, this was handled in a callous and indifferent way,” Christie said at a press conference earlier this month. “I knew nothing about this until it started to be reported in the papers about the closures. But even then, I was told it was a traffic study.”

As CBS 2’s Christine Sloan reported, Christie has always insisted that he knew nothing about the September closure of local toll lanes leading to the bridge until after the fact.

“I knew nothing about this until it started to be in the papers about the closures, but even then I was told it was a traffic study,” he said.

Zegas’ letter contends some of what the governor said at his Jan. 9 press conference was inaccurate.

“Mr. Wildstein contests the accuracy of various statements that the governor made about him and he can prove the inaccuracy of some,” the letter added.

The Christie administration denied this claim in Friday evening’s statement.

“The Governor denies Mr. Wildstein’s lawyer’s other assertions,” the statement concluded.

During the governor’s marathon press conference after the scandal erupted, he denied press accounts portraying him and Wildstein as longtime pals, CBS 2’s Tony Aiello reported.

“David and I were not friends in high school, we were not even acquaintances in high school,” Christie said at the time. “We went 23 years without seeing each other and in the years we did see each other, we passed in the hallways.”

Aiello reported that the Wall Street Journal has posted photos of Christie and Wildstein laughing together at an event on Sept. 11, which was one of the days the lanes were closed and traffic was snarled in Fort Lee.

U.S. Rep. Bill Pascrell (D-N.J.), who represents Fort Lee, told WCBS 880 on Friday evening that he had read the email from Zegas and the governor’s response.

“Obviously, somebody didn’t tell the truth and we’re going to find out who it is. When you don’t tell the truth, that’s not necessarily breaking the law but on the other hand, you’re losing more and more of the confidence of the people and that’s the situation we face now,” said Pascrell.
