A staffer who worked for New Jersey Governor Chris Christie has denied any knowledge or involvement in the Bridgegate scandal.

Christina Renna testified yesterday before a legislatie panel investigating the George Washington Bridge lane closures.

Renna worked for former deputy chief of staff Bridget Anne Kelly, who was fired over her alleged involvement in the scandal.  Renna told the panel that in September, she emailed Kelly to tell her that Fort Lee Mayor Mark Sokolich had complained about the traffic problems in his city.

Kelly responded, "Good."

Then in December, Kelly asked Renna to delete that response.  Renna did as told, but kept a copy of the email because she thought the request was strange.

Renna described Kelly as overwhelmed and insecure.  For those reasons, Renna told the panel she didn't believe that Kelly orchestrated the lane closures.

An investigation by lawyers hired by the governor's office pinned the blame for the scandal on Kelly and former Port Authority official David Wildstein.

Governor Christie has denied any involvement in the Bridgegate scandal.
