The main purpose of this legislation is to prevent the use of federal funds to implement a specific rule by the Department of Homeland Security (DHS) known as the "Public Charge Ground of Inadmissibility." This rule has been criticized for potentially harming immigrants and their families by making it harder for them to access essential services like food, medical care, and housing. Key provisions of the legislation include a clear restriction that no federal funds can be used to enforce or carry out the public charge rule.
