Part of the Department of Justice, the United States Attorneys serve as the nation’s principal litigators under the direction of the Attorney General. Ninety-three attorneys are stationed throughout the US, as well as Puerto Rico, the Virgin Islands, Guam and the Northern Mariana Islands, representing the chief federal law enforcement officer within their jurisdiction. US Attorney’s Office districts are synonymous with the judicial districts within the United States. US Attorneys are all appointed by the President for four-year terms, and thus they serve at his pleasure. In 2007, the US Attorneys became the focal point of the one biggest controversies of the Bush administration when it was revealed that several prosecutors were allegedly fired for political reasons. The scandal resulted in the resignation of Attorney General Alberto Gonzales.
