Mobilizing Against Sanctuary Cities Act

HR 780, the "Mobilizing Against Sanctuary Cities Act," blocks federal funding for state and local governments that refuse to share immigration information with federal authorities under existing law (8 U.S.C. 1373). It requires the Attorney General to annually identify non-compliant jurisdictions and report them to Congress, with affected areas losing all federal funding for at least one year until compliance is certified. The bill directly impacts local governments that do not cooperate with federal immigration enforcement, such as those with policies limiting information sharing. This policy change creates a direct financial penalty for non-compliance, replacing discretionary federal funding with a mandatory cutoff.
