Taxpayers' bill reaches $10M for Christie's bridge case fees

The updated total became known late Friday after the state released details for the first time on the more than $2 million paid over the past two years to a firm that's also owed money by the Republican governor's 2013 re-election campaign.

Invoices released by the state attorney general's office show the governor's office spent $2.3 million on digital forensics firm Stroz Friedberg, in addition to the previously disclosed $8 million Christie's administration spent through December for services from the Gibson, Dunn & Crutcher firm.

Christie's 2013 campaign treasurer, Ron Gravino, confirmed in an email that the debt is outstanding and said state election law prohibits it from being forgiven.

Leland Moore, a spokesman for the attorney general's office, said the governor's office is using Stroz Friedberg "because of the wide-ranging subpoenas it received from the Legislature and the United States Attorney's Office and the many different systems and devices from which potentially responsive documents had to be gathered."
