One thing you should note that I believe is unfair in what you posted about the IG report: In your posting you referred to the reference in the IG report that I supposedly “refused to cooperate” with the investigation. That is categorically untrue and is another example of the misrepresentations in the report. OPR asked to interview me. I told them (in a written response) that I would be happy to answer any and all questions they had and to do it in writing if they gave me the opportunity to review any documents or emails they wanted to question me about. After all, they were asking me about events that were 4 to 5 years in the past and almost three years since I had left Justice. They refused. So saying I refused to cooperate is simply untrue. I made what most lawyers would consider to be a perfectly reasonable request that they dismissed. The fact that they did not truthfully relate what actually happened in this regard should tell you something about this report and the people who wrote it.

He also wrote this piece on voter id in the Wall Street Journal.
