Lawmakers Push Shut Down Sanctuary Policies Act Targeting Cities Ignoring ICE Detainers

(LOS ANGELES, NEW YORK) — House Judiciary Committee members debated and advanced Rep. Tom McClintock’s Shut Down Sanctuary Policies Act on March 5, 2026, putting a fresh spotlight on a Republican push to override local limits on federal immigration enforcement.

The bill, HR 7640, would supersede state and local laws that restrict federal immigration agents’ activities, including policies tied to ICE detainers and rules limiting the sharing of immigration status information. It also would withhold law enforcement funding from non-compliant jurisdictions such as Los Angeles and New York and reallocate that money elsewhere.

McClintock, a California Republican, framed the measure as a direct challenge to sanctuary-style rules that local officials use to limit cooperation with federal immigration authorities. Committee action on March 5 moved the proposal forward, as parallel House and Senate bills press similar demands with different enforcement tools.

Republicans have spent weeks pressing multiple legislative tracks aimed at restricting sanctuary policies, combining funding conditions with criminal penalties and new notification requirements. Supporters argue the measures close gaps that allow people accused of crimes to avoid federal custody.

Democrats and immigrant-rights advocates have called the effort unconstitutional, arguing it amounts to federal overreach into state and local governance. They have cited states’ rights claims, the 10th Amendment, and the anti-commandeering doctrine, which limits the federal government’s ability to force state and local officials to carry out federal policy.

The committee debate over HR 7640 came as other Republican-led bills moved in parallel, including proposals that explicitly criminalize actions by state or local officials who impede federal enforcement. Those measures share an underlying goal of increasing local cooperation with immigration arrests and detention requests.

Rep. Lance Gooden, a Texas Republican who introduced the End Sanctuary Cities Act, proposed making it illegal for officials to impede federal immigration enforcement, harbor undocumented immigrants, or withhold records. The House bill would require pre-release notifications to federal authorities, and it adds criminal penalties if released individuals later kill or injure someone.

In the Senate, Sen. Lindsey Graham, a South Carolina Republican, introduced the End Sanctuary Cities Act of 2026 on January 29, 2026, and updated it on February 9, 2026, after White House consultation. Graham’s proposal imposes criminal penalties on officials who ignore Department of Homeland Security detention requests for criminal undocumented immigrants, and he has pushed to align a vote with FY2026 DHS appropriations.

“The end is near for the lawlessness and fraud enabled by sanctuary cities,” Graham said.

Sen. Eric Schmitt, a Missouri Republican, introduced a separate Senate bill on March 5, 2026, that conditions federal dollars on immigration enforcement cooperation. Schmitt’s measure also penalizes obstruction of federal officers with up to five years in prison.

Together, the proposals illustrate a Republican strategy that varies the pressure points. Some bills rely on funding conditions, while others emphasize criminal penalties or mandated notifications before a person’s release from custody.

Opponents have targeted the same pressure points in their response, arguing that Congress cannot use money to coerce local governments into carrying out federal immigration enforcement. They have also argued that criminal penalties aimed at local officials collide with constitutional limits on federal power over local governance.

Critics have pointed to earlier sanctuary-related lawsuits against Trump executive orders as a warning sign for future litigation. In one cited case, a coalition of 16 jurisdictions filed for an injunction on March 17, 2025, arguing that funding conditions defy the Spending Clause.

McClintock’s bill advanced favorably from committee even as Democrats and advocates labeled the approach “blackmail” and argued that it violates constitutional protections for state and local decision-making. The debate has centered on whether Congress can tie law enforcement funding to cooperation with immigration enforcement, particularly when local rules restrict actions such as honoring ICE detainers.

The American Civil Liberties Union has also urged opposition to a separate proposal, H.R. 32, the Defund Our Communities Act. The ACLU has warned that the measure would cut funds for schools, hospitals, and more in over two dozen states.

Supporters of the sanctuary crackdown have argued that local policies make it harder for federal authorities to detain and remove people accused of crimes. Opponents have countered that the bills risk diverting local resources, chilling cooperation with police, and cutting funding tied to essential services.

Local governments have also responded with steps that seek to reinforce their own limits on federal activity, highlighting the tension between federal proposals and city-level policy. New York City offered a clear example on Friday.

Mayor Zohran Mamdani signed the Protecting New Yorkers from Abusive Immigration Enforcement executive order on March 6, 2026. The order bars ICE from city property — including schools, shelters and hospitals — without judicial warrants, enhances data privacy, and creates an interagency crisis committee.

Mamdani’s order arrived as activists renewed pressure for a New York City Trust Act, a city-level measure that would add enforcement mechanisms. The campaign has focused on allowing lawsuits against city-ICE coordination violations by the New York Police Department and the city’s Department of Correction under former Mayor Eric Adams.

Organizer Jim Talbott of Jews for Racial & Economic Justice called for closing such coordination, as advocates pressed for limits that go beyond existing practice. The clash in New York has become a shorthand for what may play out elsewhere if Congress advances bills like HR 7640, the End Sanctuary Cities Act, and the Senate proposals.

Supporters have cited public safety in arguing for a federal response to sanctuary rules. Attorney General Pam Bondi has argued that sanctuary policies in 12 states and dozens of cities shield criminals and put communities at risk, with supporters pointing to examples that include Minnesota jurisdictions.

Opponents have cited research they say cuts the other way, using it to argue that sanctuary policies do not increase crime and may improve public safety by encouraging cooperation with law enforcement. Studies cited by opponents say sanctuary areas have 35.5 fewer crimes per 10,000 people and higher crime reporting by immigrants.

The competing claims reflect the different questions the studies and policy arguments try to address. Supporters emphasize whether local rules allow a person to leave custody before federal authorities can take action, while opponents emphasize whether immigrants feel safe reporting crime and working with police.

Graham has also linked enforcement demands to proposed changes inside federal immigration enforcement. He has advocated pairing new sanctuary enforcement with ICE reforms like body cameras, positioning oversight and enforcement as complementary parts of the same debate.

That argument emerged in a political exchange that included a February 4, 2026, letter from Democratic leaders Hakeem Jeffries and Chuck Schumer. The letter became part of the back-and-forth over how far enforcement should go, and what constraints should apply to immigration operations.

Senate Majority Leader John Thune has committed to a vote on Graham’s bill, signaling that the Senate could take up the issue as lawmakers consider FY2026 DHS appropriations. That timeline has given supporters a procedural opening, as they try to attach sanctuary-related measures to must-pass spending decisions.

For House Republicans, HR 7640’s committee advancement marks a step toward a broader floor fight over federal power and local control. The bill’s central mechanism is financial pressure, with funding withheld from jurisdictions that do not comply and reallocated elsewhere.

The funding fight remains central because it directly affects local law enforcement budgets and, by extension, city and county governance. It also invites renewed constitutional challenges from jurisdictions that argue the federal government cannot compel their cooperation through threats to essential funding streams.

New York City’s action shows local officials preparing for that confrontation, particularly around access to city facilities, warrant requirements, and data privacy. The executive order also highlights how cities can create internal structures, such as crisis coordination, when they anticipate heightened federal activity.

Los Angeles, cited as a jurisdiction that could face funding consequences under HR 7640, stands as another focal point in the national sanctuary debate. The bill’s supporters have promoted it as a way to strip away restrictions they say block federal work, while opponents have argued it punishes local communities.

The legislative path now depends on decisions that can quickly reshape the political terrain, including rules and floor scheduling in the House and the handling of amendments that could sharpen or soften enforcement provisions. In the Senate, the push to tie action to FY2026 DHS appropriations keeps timing at the center of the strategy.

Even as lawmakers set up votes, the debate has already spilled into city halls and advocacy campaigns, where officials and organizers prepare for conflict over ICE detainers, access to local facilities, and how local agencies share information. New York’s order, signed on March 6, underscores that the sanctuary fight now runs through both Capitol Hill procedure and on-the-ground governance.
