In today's Washington Post, Attorney General Alberto Gonzales gives us a preview of his Tuesday Senate testimony defending his role in the U.S. Attorney firings.

  Gonzales writes that the firings resulted from "a well-intentioned management effort to identify where, among the 93 U.S. attorneys, changes in leadership might benefit the department, and therefore the American people." He also states: "I know that I did not -- and would not -- ask for the resignation of any U.S. attorney for an improper reason. Furthermore, I have no basis to believe that anyone involved in this process sought the removal of a U.S. attorney for an improper reason."

  Notably, however, Gonzales does not explain in the op-ed what he considers an improper reason to fire a U.S. Attorney. He also does not explain why he thought these changes in leadership might benefit the American people. Stay tuned . . .
