Since she was first elected in 2004 as South Dakota's lone member of Congress, Rep. Herseth Sandlin has prioritized issues important to the state.

Her position on the Natural Resources Committee allows her to focus on issues affecting South Dakota's public lands, including the Black Hills National Forest, as well as issues critical to the nine sovereign Native American tribes she represents, issues like law enforcement, health care and infrastructure essential to economic development. In addition, during the 110th Congress, Rep. Herseth Sandlin was selected to serve as one of just 15 members on the Select Committee on Energy Independence and Global warming, in recognition of her leadership on and advocacy for renewable biofuels.
