Mobilizing Against Sanctuary Cities Act

This bill would require the Attorney General to annually identify state or local governments that fail to comply with federal immigration cooperation laws, such as sharing immigration status information or honoring detainer requests. Jurisdictions found non-compliant would lose eligibility for all federal financial assistance (including grants and programs) for at least one year. The law mandates annual reports to Congress and allows any member of Congress to request compliance reports on specific jurisdictions. It directly affects cities, counties, and states that do not follow federal immigration enforcement directives.
