(CNN) - New Jersey Gov. Jon Corzine's campaign is staying on the attack, releasing a fresh negative ad that charges Republican rival Chris Christie has "one set of rules for himself, another for everyone else."
"While he was U.S. Attorney, Republican Chris Christie gave one of his subordinates a $46,000 loan. And even though it is required under federal and state laws, Christie never reported the loan. And never paid taxes on the interest he received," says the narrator in the 30-second spot.
"When he was caught, Christie said it was a 'mistake.' But he prosecuted people who did the same things. Chris Christie. One set of rules for himself. Another for everyone else."
Christie has denied any impropriety, calling the omission an inadvertent oversight, and telling reporters he plans to update his taxes and all other relevant filings.
