The new story on Chris Christie, the former U.S. Attorney and current Republican nominee for Governor of New Jersey, just keeps getting worse, the New York Times reports -- now involving his tax returns.

It was revealed that Christie had failed to reveal in his state and federal financial disclosure forms that he'd made a $46,000 loan to an assistant in the U.S. attorney's office, Michele Brown, who still works in the U.S. Attorney's office and is still paying off the loan to him in regular installments. The loan was secured by a second mortgage on Brown's home.

Now the Times has discovered that Christie failed to report income from the loan on his tax returns. Christie aides told the Times that Christie will file an amended tax return.

This story is sure to give Democratic Gov. Jon Corzine a lot of ammunition. Combined with the news about Christie's conversations years ago with Karl Rove about a potential bid for governor, these stories could seriously damage Christie's reputation as a squeaky clean corruption-busting prosecutor, which has been a cornerstone of his political career.
