The documents being withheld pertain to an investigation of Baker's $10,000 contribution to the New Jersey Republican State Committee. The contributions came just months before Christie officials gave Baker's company, General Catalyst, a contract to manage New Jersey pension money. New Jersey's pay-to-play rules prohibit contributions to state parties from "any investment management professional associated" with a firm managing state pension money. 

When the campaign donations and subsequent pension contract came to light in May, Democrats criticized Baker, who was then launching his 2014 campaign for governor of Massachusetts. In response, New Jersey launched a formal investigation into Baker's contributions. The Newark Star-Ledger reported at the time that Christie officials "said the review would take several weeks."

Five months later, with Baker now neck-and-neck in the polls with Democratic Attorney General Martha Coakley and backed by more than $5 million from the Christie-led RGA, Christie officials have denied an open records request for the findings of the investigation. 

In a reply to International Business Times' request for the findings of the audit under New Jersey's Open Public Records Act, Christie's Treasury Department said the request is being denied on the grounds that the documents in question are "consultative and deliberative material." Despite officials' assurances in May that the probe would take only weeks, the New Jersey Treasury said in September that the investigation is still "ongoing" -- a designation the department says lets it stop the records from being released.
