The Milwaukee County District Attorney is a state constitutional officer responsible for criminal prosecution in Milwaukee County, Wisconsin. The current district attorney is John T. Chisholm, who has served since 2007.
The first Milwaukee County District Attorney was Charles James, who served a two-year term beginning in 1848. District attorneys from then until 2008 also served two-year terms in office. Since that year, the district attorney serves for four years. The position is not, and has never been, subject to term limits.
In the first decade of the 1900s, district attorney Francis E. McGovern and his office investigated and prosecuted corrupt city officials. The administration of Mayor David Rose was notorious for this, often ignoring illegal activity. Rose, although termed by McGovern "the self-elected, self-appointed attorney general" of local crime, was not indicted but was defeated in the 1910 mayoral election by Socialist Emil Seidel.
The district attorney's office is responsible for prosecuting state-level criminal offenses committed in Milwaukee County. The office also prosecutes county ordinance violators. Separate units within the office prosecute offenses such as violent crimes, sexual assault, domestic violence, white-collar crimes, and drug-related crimes, among others. The office also contains a unit devoted to prosecuting misdemeanor offenses.
The district attorney's office is composed of about 125 assistant district attorneys, who are supervised by four deputy district attorneys and a chief deputy district attorney. The office is assisted by a relatively large support staff, and has ten investigators, who are law-enforcement officers.
