The Trump administration’s legal campaign against sanctuary cities and states is expanding at a pace unlike anything seen in previous administrations, with the Justice Department now having filed 27 lawsuits targeting more than 20 cities, counties, and states since January 2025. The conflict cuts to a fundamental constitutional question: whether local governments can legally obstruct federal immigration enforcement, and who ultimately bears responsibility for public safety when they try.
A Broadening Legal Offensive
Within just the past three months, the DOJ has filed suit against Connecticut, Maryland, New Jersey, New York, a county in Michigan, and the city of Philadelphia. The cases challenge a variety of local and state policies that restrict how immigration authorities can operate within those jurisdictions. These policies typically limit cooperation between local law enforcement and Immigration and Customs Enforcement, prohibit officers from asking about immigration status, and in some cases bar ICE agents from concealing their identity or operating in unmarked vehicles.
Some of these sanctuary policies date to the 1980s, making them deeply entrenched in local political culture. The breadth of the administration’s legal push signals it is not content to negotiate or apply political pressure alone — it is taking the fight directly to federal courts.
By the Numbers
27 — total DOJ lawsuits filed against sanctuary jurisdictions since January 2025.
20+ — cities, counties, and states named as defendants across those cases.
6 — at least a half-dozen new suits in just the past three months.
7 — ICE-related bills passed by the Philadelphia City Council in April 2025, six of which are now in effect.
17 — Maryland county sheriffs who filed their own lawsuit in May to block their state’s sanctuary law before the federal government did.
Mixed Results in Court
The administration has seen both setbacks and early wins in federal courts. In June 2025, a Biden-appointed U.S. district judge in New Jersey dismissed the DOJ’s lawsuit against four cities — Hoboken, Jersey City, Newark, and Paterson — that had been sued in May. That ruling was a blow to federal enforcement efforts in the state.
In Pennsylvania, however, a Trump-appointed district judge issued a preliminary injunction blocking Philadelphia’s policy barring masked officers and the use of unmarked vehicles by ICE. That ruling keeps a key enforcement tool available to federal agents while the broader legal battle plays out.
Maryland at the Center
Maryland has become a flash point. A state law that took effect May 31 bars both state and local officers from asking individuals about immigration status or holding someone for suspected immigration violations unless a warrant or court order is in hand. The DOJ moved last week to sue the state and halt the law.
Notably, local law enforcement within Maryland is itself divided on the issue. Sheriffs from 17 of the state’s counties sued their own state government in May, seeking to stop the law before it took effect. That internal conflict — local sheriffs wanting to cooperate with federal immigration enforcement while state law blocks them — illustrates exactly the friction the Trump administration is trying to resolve through the courts.
Democratic state Sen. Clarence Lam defended the policy, arguing that “our state taxpayer dollars should not go towards having local law enforcement enforce federal immigration law.” Supporters of these policies often frame them as community safety measures. Cassandra Charles of the National Immigration Law Center argued that “these sanctuary policies are most times created to help make communities safer.”
Critics counter that shielding illegal immigrants from federal law enforcement puts American communities at greater risk and undermines the rule of law that all residents depend on.
The Broader Stakes
The administration’s strategy of sustained legal pressure sets a national precedent. If federal courts ultimately rule that localities cannot obstruct ICE operations, it would reshape the legal landscape for sanctuary jurisdictions across the country. Conversely, a string of dismissals could embolden states and cities to expand such protections. With Senate control still in play heading into 2026, the political stakes of that outcome are equally significant.
What is beyond dispute is that the federal government’s willingness to use the courts as an enforcement mechanism against non-cooperating jurisdictions represents a major escalation — one that will likely take years and multiple appellate rulings to fully resolve.
