A new report details how a $30 million tax debt that Trump casinos owed New Jersey was settled for far less after Gov. Chris Christie took office.

Before the settlement for $5 million, The New York Times reports that for several years lawyers and auditors had been fighting to collect overdue taxes owed by Trump's casinos, which had grown to $30 million including interest.

But the year after Christie took office, the state began to consider settlement offers. By the end of 2011, the state agreed to accept 17 cents on the dollar of what the casinos owed, the Times reported.

The move has prompted questions of special treatment, the Times reported.



The governor's office for Christie and Trump's campaign did not respond for CNBC's requests for comment.
