Christie attended a fundraiser Thursday evening for Steve Lonegan's state congressional campaign, during which he addressed the crowd of between 75 and 100 people, ABC News reported.
"It's unfortunate, it was a mistake, it was obviously upsetting," Lonegan recounted Christie saying at the event in Mountain Lakes, N.J. "He said we have 1,400 days in this administration and lots of challenges for the governing of this state and we will continue to move ahead and those successes over time will overshadow all this negativity."
Reporters were not allowed inside the event, but were allowed to speak with attendees afterward.
"I think everybody came out of this event feeling really good and also feeling that the governor is confident that he will make his way through this little blip on the screen, this scandal, so-called scandal and we think that the Democrats will be yelling and screaming long after the public has stood up for the governor and recognized he is right," Lonegan said.
Tom Considine, a former Christie administration cabinet member, also attended the fundraiser and said Christie "didn't shy away that it has been a turbulent week for the administration, but the commitment of the administration and the governor personally to remain dedicated to the work that he and the administration are committed to for the people of New Jersey are paramount."
The Christie administration has been accused of closing lanes on access roads to the George Washington Bridge, which connects Fort Lee, N.J., with New York City to punish Fort Lee's mayor, a Democrat, for not endorsing him for reelection. The administration said the closures were part of a traffic study.
Christie has fired several top aides and has denied any involvement in or knowledge of the lane closures.
