Democratic Study Group
The Democratic Study Group (DSG) is a legislative service organization (LSO) in the House of Representatives. It was founded in 1959 "as a liberal counterpoint to the influence of senior conservatives and southern Democrats, it now consists of nearly all Democratic members of the House. The oldest and best known LSO in Congress, it has the largest budget and staff. The DSG's principal activity is to disseminate detailed written materials to members of the House about upcoming legislation and policy issues, which it does on a daily basis when the chamber is in session."
