TRENTON, N.J. (AP) — New Jersey taxpayers face an $8 million tab to cover the cost of Gov. Phil Murphy’s task force investigating business tax breaks.

The Associated Press obtained the invoices through a records request.

Murphy, a Democrat, set up the task force last year after two state reports raised concerns about how business tax breaks established under Republican Chris Christie were awarded.

New York-based Walden Macht & Haran and the Quinones Law firms are conducting the investigation on behalf of Ronald Chen, a former Rutgers Law School dean, who chairs the task force.
