On January 14th, 2013, Chris Koster was sworn in for a second term as the 41st Attorney General of the state of Missouri. As Attorney General, Koster created a Domestic Violence Task Force which led to comprehensive new laws to protect domestic violence survivors; recovered a record $200 million to the state’s health care system from fraudulent Medicaid providers; cracked down on violations of workers' rights; aggressively protected Missouri consumers against fraud, including mortgage-relief and debt-settlement scams; and supported law enforcement in fighting the spread of methamphetamine and violent crime.

From 2004 to 2008, Koster represented the 31st district in the Missouri Senate, which covers Cass, Johnson, Bates and Vernon Counties.

During his time in the General Assembly, Koster played key roles in the debates over stem cell research, tort reform, and the elimination of Medicaid fraud. Additionally, in 2006 Koster successfully carried legislation in the Senate to dramatically overhaul Missouri's eminent domain laws.

Prior to his election to the Missouri Senate, Koster served as Cass County Prosecuting Attorney for ten years. He was first elected prosecutor in 1994 and was re-elected in 1998 and 2002 by wide margins.
