Karl Rove allegedly replaced these attorneys based not on their performance, but on their willingness to set aside their neutrality and pursue cases which were strictly political. Many questions must be answered, including why did the attorney general cede the decision-making regarding the assignment of US attorneys to a political operative, and did the president ask him to do this?
Far from being a “fishing expedition”, the investigation into the firing of US attorneys is a very serious matter, with implications that affect the very core of our democratic system. The erosion of the justice system affects both Republicans and Democrats, and all Americans. If the law has been compromised in this case, we must learn how it happened and ensure it doesn't happen again.
