A former top appointee of Chris Christie says there is evidence contradicting what the New Jersey governor has said publicly about the notorious George Washington Bridge traffic lane closures that have roiled the Republican's administration, according to the man's lawyer.

David Wildstein resigned his position at the Port Authority of New York and New Jersey in December amid allegations that Christie appointees had ordered access lanes to the nation's biggest river crossing in Fort Lee closed last year to punish that town's mayor politically for not endorsing Christie for reelection.

Wildstein's attorney, Alan Zegas, wrote on Friday that "evidence exists" contradicting Christie's recollection about the lane closures at a news conference earlier this month.

"Evidence exists ... tying Mr. Christie to having knowledge of the lane closures, during the period when the lanes were closed, contrary to what the governor stated publicly in a two-hour press conference (on January 9)," Zegas said in a letter to the general counsel of the Port Authority of New York and New Jersey, which operates the bridge and where Wildstein had worked for the governor.

Days of lane closures

The letter references the closures over a work week in September, but does not suggest that "evidence" contradicts anything Christie has said so far about his advisers at the time or any role they might have played in alleged political shenanigans.

The letter also does not suggest that Christie had any advance knowledge of the closings. Zegas also didn't disclose the evidence.

CNN Senior Legal Analyst Jeffrey Toobin said Zegas' letter is just that. "It's not sworn testimony. It's not proof," he said.
