On December 7, 2006, the George W. Bush Administration's Department of Justice ordered the unprecedented midterm dismissal of seven United States attorneys. Congressional investigations focused on whether the Department of Justice and the White House were using the U.S. Attorney positions for political advantage. Allegations were that some of the attorneys were targeted for dismissal to impede investigations of Republican politicians or that some were targeted for their failure to initiate investigations that would damage Democratic politicians or hamper Democratic-leaning voters. The U.S. attorneys were replaced with interim appointees, under provisions in the 2005 USA PATRIOT Act reauthorization. A subsequent report by the Justice Department Inspector General in October 2008 found that the process used to fire the first seven attorneys and two others dismissed around the same time was "arbitrary", "fundamentally flawed" and "raised doubts about the integrity of Department prosecution decisions". In July 2010, the Department of Justice prosecutors closed the two-year investigation without filing charges after determining that the firing was inappropriately political, but not criminal, saying "Evidence did not demonstrate that any prosecutable criminal offense was committed with regard to the removal of David Iglesias. The investigative team also determined that the evidence did not warrant expanding the scope of the investigation beyond the removal of Iglesias." Issues in brief By tradition, all U.S. Attorneys are asked to resign at the start of a new administration. The new President may elect to keep or remove any U.S. Attorney. They are traditionally replaced collectively only at the start of a new White House administration. U.S. Attorneys hold a political office, in which the President nominates candidates to office and the Senate confirms, and consequently, they serve at the pleasure of the President. When a new President is from a different political party, typically almost all of the resignations are eventually accepted and the positions are then filled by newly confirmed appointees, typically from the new President's party. Although a political appointee, it is essential to the effectiveness of a U.S Attorney that they are politically impartial in deciding which cases to prosecute and in arguing those cases before judges and juries with diverse views. Some U.S. Senators were concerned about a provision in the 2006 re-authorization of the USA PATRIOT Act that eliminated the 120-day term limit on interim appointments of U.S. Attorneys made by the United States Attorney General to fill vacancies.
