WASHINGTON D.C. — The Biden-era practice of engaging sanctuary jurisdictions with financial incentives is officially over. As of February 1, 2026, the Trump administration has begun withholding federal funding from so-called “sanctuary” cities and the states that host them, marking a major escalation in its immigration enforcement strategy.
President Donald Trump announced the policy shift on January 13 at a speech in Detroit, declaring that “starting Feb. 1, we’re not making any payments to sanctuary cities or states having sanctuary cities because they do everything possible to protect criminals at the expense of American citizens,” and warned that the cuts would be “significant.”
New Policy Takes Effect, Targets Broad Range of Funding
Federal agencies have been instructed to pause or condition the release of federal grant money to local governments and states that limit cooperation with U.S. Immigration and Customs Enforcement (ICE) detainers and federal immigration enforcement efforts, according to a Department of Justice memo issued last year that elaborated on the policy’s implementation.
Though specifics on exactly which funding streams will be halted have not been publicly released, federal grants tied to community policing, public safety and other discretionary programs are expected to be affected. Trump campaign and administration officials have cited local policies that restrict immigration enforcement cooperation as justification for the cuts.
Legal Precedents Raise Stakes
This effort follows earlier attempts by the Trump administration to link federal grant eligibility to compliance with federal immigration law, such as through Executive Order 14159 signed on January 20, 2025, which directed expanded immigration enforcement and funding restrictions against sanctuary jurisdictions.
Federal courts, however, have blocked similar funding conditions in the past. In 2025, a U.S. district judge in San Francisco issued a preliminary injunction that barred the administration from withholding or freezing federal funds to cities and counties labeled as “sanctuary jurisdictions,” ruling that the practice violated constitutional limits on executive power.
States and Cities Expected to Push Back
High-profile sanctuary jurisdictions and Democratic state governments have already signaled that they will pursue aggressive legal challenges. Leaders in California, Minnesota, Illinois and New York are expected to argue that the administration’s actions exceed constitutional authority by conditioning unrelated federal funds on compliance with federal enforcement priorities. Calls for injunctions and lawsuits were circulated in the days leading up to the funding cutoff.
Opposition officials contend that the federal government cannot coerce states or municipalities to enforce federal law by withholding broad categories of funds, pointing to prior federal court rulings that found such conditions unlawful.
Trump’s move has ignited debate over the balance of power between federal and local governments on immigration policy. Supporters of the cuts argue that sanctuary jurisdictions undermine federal law enforcement efforts and contribute to local crime, while critics warn that the funding restrictions threaten essential services and public safety programs in major cities.
Republican lawmakers are likely to defend the administration’s position, citing the need for cooperation with federal immigration enforcement. Democrats and municipal officials say litigation is imminent, raising the prospect that federal courts will once again be a battleground over sanctuary policy.
As the new funding policy takes effect, municipalities and states will be watching closely to see which grants are withheld and how the administration enforces compliance standards. Legal experts expect appeals and injunction motions to move quickly through the federal system, setting the stage for a potentially protracted constitutional fight in the courts.
