Attorney General Eric Holder, in his confirmation hearing:

The Department of Justice first and foremost represents the people of the United States. Not any one president, not any political party, but the people. I learned that principle in my first days at the department, when I sent corrupt public officials from both parties to jail. It guided my work as U.S. attorney for the District of Columbia, when I prosecuted one of the most powerful members of my own party at the very time he held in his hands the top legislative initiative of my own president. And it guided my service as deputy attorney general, when I recommended independent counsel investigations not just of members of the Cabinet, but of the very president who appointed me and in whose administration I proudly served.
None of those calls was easy. But I made them because I believed they were the right decisions under the law. If confirmed as attorney general, I pledge to you that this same principle will guide my service and inform every decision I make.

The news, today: “New Mexico Gov. Bill Richardson and former high-ranking members of his administration won’t be criminally charged in a yearlong federal investigation into pay-to-play allegations involving one of the Democratic governor’s large political donors, someone familiar with the case said. The decision not to pursue indictments was made by top Justice Department officials, according to a person familiar with the investigation, who asked not to be identified because federal officials had not disclosed results of the probe.”

So the guy who endorsed Obama during the primary is off the hook, but boy, Holder will bring fire and brimstone against those CIA interrogators.
