NEW YORK (Reuters) - A New Jersey Democrat leading a probe of the bridge traffic scandal that has engulfed Governor Chris Christie said on Sunday he has seen no evidence to support claims that the governor had been aware of the apparently politically motivated traffic jams as they happened.
The remarks by Assemblyman John Wisniewski, who co-leads the probe, came two days after a former Christie appointee at the agency overseeing the bridge who personally oversaw the lane closures said "evidence exists" that Christie had knowledge of the blockage when it happened.
If such evidence does exist, a state panel investigating the closures has not yet seen it, Wisniewski said.
Separately on Sunday, Christie's director of intergovernmental affairs, Christina Renna, resigned.
Renna's lawyer, Henry E. Klingeman, confirmed to Reuters that she had resigned, effective January 31.
Klingeman also said that Renna was among several top aides who have until Monday to respond to subpoenas in the scandal.
However, in a statement provided by Klingeman, Renna said she had been considering leaving since shortly after Christie's re-election last fall.
"I have spent almost four years working hard for a Governor I continue to respect and admire," Renna said in the statement. "The transition from term one to term two is a natural time to pursue an opportunity in the private sector."
Christie, who is considered a leading Republican candidate for the White House in 2016, has repeatedly denied any knowledge of a plan to snarl traffic last September in Fort Lee, New Jersey, near the busy George Washington Bridge that connects New Jersey and New York City and severed ties with several top aides over their role in the incident.
Christie has been dogged by scandal for more than a month since it emerged that several of his top aides and appointees called for lane closures leading to the busiest bridge in the United States, apparently as retribution against the Democratic mayor of Fort Lee for not endorsing the governor's re-election campaign.
Christie has repeatedly denied having any knowledge of the scheme and dismissed two of his top aides for their roles in it. Still, the scandal has hurt his image and recent polls show him losing ground as a potential presidential contender.
"A CURIOUS CHOICE OF WORDS"
David Wildstein, the Christie appointee at the agency overseeing the bridge who personally oversaw the lane closures, on Friday made the claim that "evidence exists" of Christie's knowledge of the blockage.
"We don't really know what the evidence is," Wisniewski told NBC's "Meet the Press." "He (Wildstein) submitted over 900 pages of documents in response to the subpoena. Apparently what he's talking about must be something other than what he submitted."
Wildstein resigned from the Port Authority of New York and New Jersey late last year amid the growing probe.
Wisniewski also said he was unclear from Wildstein's choice of words that Christie was aware of the closures.
"The use of the words 'evidence exists,' as opposed to saying, 'I have documents,' or, 'I have an e-mail,' it's a curious choice of words," Wisniewski said. "Maybe this is something else that is not within the scope of the subpoena the committee issued. So it raises questions about what does he have and why doesn't the committee have it?"
