The purpose of this legislation is to amend the Social Security Act to ensure that federal funds provided to states for temporary assistance to needy families (TANF) are used to enhance state spending rather than replace it. The goal is to protect the financial support available to families in need by making sure that federal assistance is added to what states already provide, rather than substituting for it. Key provisions of the legislation include a clear requirement that states must use federal TANF funds to supplement their own spending.
