The main purpose of this legislation is to improve the distribution of funds from the Temporary Assistance for Needy Families (TANF) program by ensuring that financial support is specifically directed to families that are most in need. The goal is to help low-income families by providing them with the necessary assistance and services to improve their financial situation. Key provisions of the legislation include a requirement that states receiving TANF grants must only use these funds to assist families whose income is less than twice the federal poverty level.
