Trump has mostly lost challenges against – Donald Trump’s administration is launching a renewed legal campaign to counter the policies of states and cities that have resisted his immigration agenda. Despite a series of setbacks in federal courts, the Trump team is leveraging new lawsuits to challenge sanctuary measures, raising fresh legal arguments about the balance of power between state and federal authorities. These cases, filed by the Justice Department, aim to address issues such as the use of unmarked license plates by immigration agents and the enforcement of local policies that limit cooperation with federal deportation efforts.
Recent rulings have consistently favored states and cities that have implemented sanctuary policies. For example, a federal judge recently dismissed a Trump-led challenge to Boston’s ordinance, which restricts local law enforcement from sharing specific immigrant information with Immigration and Customs Enforcement (ICE). This decision marked the fourth time in Trump’s second term that a case targeting Democratic-led jurisdictions was ruled against. The administration’s approach has faced similar hurdles in previous years, but it continues to press forward, even as appeals are pending.
Acting Attorney General Todd Blanche highlighted the strategic challenges of these lawsuits, noting that they are often heard in cities with a reputation for judicial resistance to Trump’s policies. “The challenge with these sanctuary city lawsuits is that we have to file them in the sanctuary city, where the bench is terrible – for the most part – on these issues,” he said during an interview with Sean Hannity. Blanche’s comments underscore the administration’s frustration with federal judges who have consistently ruled against Trump’s efforts to enforce his immigration priorities. However, he remains optimistic about the Supreme Court’s potential role in overturning these decisions.
“I think the administration feels, politically, that this is a winning issue,” remarked Harry Sandick, a legal expert who worked against Trump’s sanctuary city initiatives during his first term. “This is an administration that is willing to lose in court, as they have done repeatedly, if they believe there is a political benefit for pressing a particular rule or policy.”
While the Supreme Court has yet to take up major cases, its recent decisions have signaled a shift in the legal landscape. In June 2025, the high court declined to hear a case against California’s sanctuary laws, which had been previously rejected during Trump’s first term. This inaction leaves the door open for further challenges, particularly as the administration explores novel legal angles to assert federal authority.
One of the latest developments involves disputes over mask bans for federal agents. In a February 2025 lawsuit against Chicago and Illinois, the Justice Department targeted policies that restrict the use of unmarked license plates, a tactic they argue hampers immigration enforcement. This case, part of at least nine legal actions by the second Trump administration, focuses on states like Illinois and California, which have resisted cooperating with federal deportation efforts. The lawsuit against Los Angeles, filed in June 2025, emphasizes how sanctuary policies are designed to impede federal immigration officers’ ability to operate within those jurisdictions.
Legal experts suggest that some of the newer lawsuits may offer more favorable outcomes for Trump. Matt Crapo, director of litigation for the Federation of Immigration Reform, noted that states are now taking a more active role in interfering with federal operations. “Some sanctuary policies are, ‘Hey, we’re not going to help the feds, but we’re not going to interfere with how the feds are going to do their job,’” Crapo explained. “And then the newer, more recent cases are, states are actually trying to tell the feds how to do their job.”
The Trump administration’s strategy has evolved since 2025, when it resumed its push against sanctuary policies. In February 2025, the Justice Department filed its first lawsuit targeting Chicago and Illinois, a move that set the stage for nine additional challenges across the country. These cases are centered on prohibitions that prevent state and local officials from sharing information with federal agencies, such as the release dates of undocumented immigrants arrested or detained by local authorities.
Other policies under scrutiny include local governments refusing to honor detainer agreements. These requests, made by federal agents, ask for individuals in local custody to remain detained beyond their release dates to be transferred for immigration proceedings. Some cities have also implemented blanket bans on using resources to assist in civil immigration enforcement, further complicating the federal government’s efforts to deport undocumented immigrants.
Although half of the pending cases are still in the judicial pipeline, the administration remains undeterred. Legal analysts suggest that the focus of these lawsuits may shift from purely defensive measures to more aggressive assertions of federal power. The Justice Department’s June 2025 lawsuit against Los Angeles, for instance, highlights how sanctuary policies are framed as deliberate obstacles to immigration enforcement. A judge is expected to rule on this case in the coming weeks, potentially setting a precedent for future litigation.
With the Supreme Court avoiding major rulings on sanctuary laws, the legal battle has intensified at the district court level. The administration’s persistence in these cases reflects its broader goal of redefining the relationship between state and federal authorities in immigration matters. Even as the courts have largely sided with sanctuary cities, Trump’s team continues to argue that these policies undermine the federal government’s ability to carry out its deportation agenda.
The ongoing lawsuits reveal a strategic pivot in the administration’s approach. While earlier efforts focused on coercing states into compliance, recent cases emphasize how states are actively shaping the rules of engagement for federal immigration enforcement. This dynamic has created a new legal battleground, where the question is no longer just about cooperation but about the extent to which local governments can dictate the terms of federal operations.
