A New Jersey judge has refused to enforce Bridgegate subpoena compliance against two top aides to Gov. Chris Christie, finding their exercise of the Fifth Amendment privilege valid.

Mercer County Assignment Judge Mary Jacobson held Wednesday that the New Jersey Legislative Select Committee on Investigation cannot compel Christie’s former deputy chief of staff, Bridget Kelly, and his two-time campaign manager, Bill Stepien, to provide documents that could be used against them in an ongoing criminal investigation by the U.S. Attorney’s Office.
