The Department of the Interior serves a number of functions: it manages public lands, it administers a range of domestic programs, and it handles federal relations with American Indians. In relation to this last function, Republicans inserted a provision in the Interior funding bill for 2003 that established a commission to study Indian gaming. Progressives opposed this provision because they saw it as a way to undermine an industry that was permitted according to existing law and that had benefited a number of tribes. They supported a Hayworth (R-AZ) amendment that struck this gaming provision from the funding law. The amendment was adopted 273-151.
