Several U.S. sanctuary cities and states have drawn sharp criticism for policies that lead to the release of undocumented immigrants with criminal records, allowing some to commit further serious crimes. The Department of Homeland Security has highlighted cases in New York City, Illinois, Minnesota, and Fairfax County, Virginia, as particularly concerning. Federal authorities, including ICE, have responded with operations and lawsuits against these areas.
Sanctuary policies in certain U.S. jurisdictions limit cooperation with federal immigration enforcement, preventing local police from notifying Immigration and Customs Enforcement (ICE) about the impending release of undocumented immigrants from jails and restricting federal access to interview suspects. The Trump administration has filed lawsuits against several such areas, including Minnesota, New York City, Boston, Illinois, and Los Angeles, challenging these practices.
In New York City, local authorities have released approximately 7,000 undocumented immigrants since President Trump's inauguration without honoring ICE detainer requests. According to the Department of Homeland Security, these individuals were later linked to nine homicides, 2,509 assaults, 199 burglaries, 305 robberies, 392 dangerous drug offenses, 300 weapons offenses, and 207 sexual predatory offenses. One case involved Mario Bustamante-Leiva, a 49-year-old Chilean national, who was arrested in New York for purse snatching weeks before allegedly stealing Homeland Security Secretary Kristi Noem's purse in Washington, D.C., in April; he was released on a desk appearance ticket and failed to appear in court. Another incident in July saw two Dominican nationals, Christhian Aybar-Berroa, 22, with eight prior arrests and a 2023 deportation order, and Miguel Francisco Mora Nunez, 21, facing charges including assault on a pregnant woman and threats with a machete, accused of shooting an off-duty Customs and Border Protection officer.
Illinois has released over 1,700 criminal undocumented immigrants with ICE detainers since Inauguration Day. In September, the administration launched "Operation Midway Blitz" targeting Chicago, where ICE holds detainers on about 4,000 individuals in state custody. Chicago Mayor Brandon Johnson established "ICE-free zones," and in October, local police reportedly stood down during an incident in Broadview where Border Patrol agents were rammed by vehicles and confronted an armed suspect, leading to defensive gunfire.
In Minnesota, an ICE operation in Minneapolis yielded around 400 arrests. Mayor Jacob Frey stated, "Officers will not coordinate with any federal agency that is doing immigration law enforcement work." Governor Tim Walz criticized ICE, comparing it to "Trump’s modern-day Gestapo." A notable case involved Somali national Abdimahat Bille Mohamed, released after pleading in two sexual assault cases, who then allegedly raped a minor, multiple adults, and kidnapped and raped a woman; Attorney General Pam Bondi remarked, "If Minnesota will not protect its own people, the Department of Justice will do it for them."
Fairfax County, Virginia, released Salvadoran migrant Marvin Morales-Ortez, 23, a suspected MS-13 member who entered illegally in 2016 and whose 2022 deportation case was dismissed. Despite prior charges including a dropped 2021 murder accusation, unpaid theft fine, and recent gun and assault charges that were dropped, he allegedly murdered a man in Reston less than 24 hours after release. He was rearrested after a manhunt. The Department of Homeland Security stated, "The sanctuary politicians of Fairfax County, VA have blood on their hands."
