This proposed legislation seeks to amend chapter 93 of title 18, United States Code, by creating a new section, 1925, to prohibit the obstruction of immigration laws by official interference . It specifically targets officers, employees, or contractors of State or local governments who, acting under color of law and with intent to impede federal enforcement, engage in certain prohibited conduct. The bill outlines several unlawful actions, including restricting federal immigration officers from accessing detention facilities, knowingly concealing or harboring aliens, or facilitating the release of an alien subject to removal without providing federal authorities with 48 hours notice and an opportunity to assume custody. It also prohibits policies that restrict State or local law enforcement from cooperating with federal immigration authorities, such as sharing information or complying with lawful requests from the Department of Homeland Security, including detainers. Violations of these provisions carry severe penalties, with fines and imprisonment varying based on the outcome. If a violation results in the release of an alien who subsequently commits an act leading to the death of any person , the offender faces imprisonment for any term of years or for life; acts leading to serious bodily injury carry up to 20 years imprisonment, while other violations are punishable by up to 10 years imprisonment.
