End Sanctuary Cities Act of 2026

This bill amends chapter 93 of title 18, United States Code, to prohibit the obstruction of immigration laws through official interference. It makes it unlawful for any responsible executive official of a State or unit of local government to knowingly prohibit or restrict compliance with formal Department of Homeland Security (DHS) requests. These requests pertain to reasonable advance notice regarding the release of a criminal alien , including through the establishment or enforcement of pertinent laws or policies. The legislation defines a criminal alien as an alien charged with or convicted of a Federal or State crime, and reasonable advance notice as at least 48 hours prior to release, if practicable. Violations of this prohibition carry significant penalties, which are tiered based on the severity of the criminal alien's offense. For instance, if the released alien was charged with or convicted of murder, rape, or a sex offense against a minor, officials face 10 to 25 years imprisonment. Lesser offenses, such as serious violent felonies or other federal/state crimes, result in shorter imprisonment terms, ranging from 30 days to 10 years, in addition to potential fines. A severability clause ensures that if any provision is found invalid, the rest of the Act remains in effect.
