The panel's investigation has been on pause awaiting the U.S. attorney's investigation into the matter. On Monday, former Port Authority of New York and New Jersey official Bill Baroni and Bridget Kelly, former deputy chief of staff to Gov. Chris Christie, pleaded not guilty to charges they orchestrated politically motivated lane closures in September 2013. The scandal touched off efforts in both states to reform the Port Authority, which has earned a poor reputation in many lawmakers' minds. Republican Assemblyman Michael Patrick Carroll pointed out the committee was formed with a broad investigatory mandate and said it should move forward with its probe of the Port Authority. Lawmakers said the failure to subpoena testimony likely limited their inquiry, and some Republican members are skeptical about why the committee may have to meet again.
