Remind us again just what those were.
Here is some of the ammo I mentioned that would be used against him all over again pulled from Wikipedia:
"Gingrich was accused of hypocrisy and unethical behavior when he accepted a $4.5 million advance as part of a book deal, in light of his previous role in the investigation of Jim Wright. Following the accusations, Gingrich returned the advance."
"Including charges related to the book deal, Democrats filed 84 ethics charges against Speaker Gingrich during his term, including claiming tax-exempt status for a college course run for political purposes and using the GOPAC political action committee as a slush fund. All charges were eventually dropped following an investigation by the Republican-led House Ethics Committee. However, Gingrich admitted to "unintentionally" giving inaccurate information to the House Ethics Committee during the course of the investigation. The committee did not indict him on charges of intentional perjury.[9] The matter was settled when he agreed to reimburse the Committee $300,000 for the cost of prolonging the investigation. The payment was described as a "cost assessment" and not a fine by the Committee.[10] He also agreed to not "spin" the story in the media, but admit publicly to his transgressions."
