The Act seeks to eliminate sanctuary city policies by requiring cooperation with federal immigration enforcement, outlining exceptions for crime victims and witnesses, and rendering sanctuary jurisdictions ineligible for certain federal funds. It aims to withhold funding from sanctuary cities that release criminal aliens who commit offenses in other states, allowing the affected state's Attorney General to seek injunctive relief to withhold grant funding. The bill also amends immigration law to exclude sanctuary jurisdictions from certain government funding and loans. It emphasizes consequences for releasing criminal aliens leading to crimes in other states, allowing the Attorney General to seek to withhold federal funding from the releasing jurisdiction.
