Homeland Security says New York failed to honor 16,070 ICE detainers tied to 52,503 criminal charges and convictions, and named Mayor Zohran Mamdani and Gov. Kathy Hochul for standing in the way.
The Department of Homeland Security took to social media on Monday and drew a hard line against New York’s refusal to cooperate with Immigration and Customs Enforcement. In a post highlighted by Breitbart News, the agency said the state has left thousands of detainers unanswered while criminal charges pile up.
DHS put the numbers on the record for the period from January 20, 2025, to October 8, 2026. New York, it said, failed to honor 16,070 ICE detainers. Those cases carried 52,503 total criminal charges and convictions.
The agency did not soften the point. It named New York City Mayor Zohran Mamdani and New York Gov. Kathy Hochul directly and framed their posture as an obstacle to basic enforcement.
"We enforce these laws with no help from Mayor Mamdani and Governor Hochul,"
DHS stated in the same post, before laying out the detainer count and the associated criminal totals.
Officials also tied the Monday blast to a larger Trump Administration pledge. The department said it would keep pressing the mission in every city and state.
"The Trump Administration is committed to protecting the American people in every city and every state, and we won’t let sanctuary politicians stand in our way."
That language put sanctuary non-cooperation at the center of the fight, not at the margins.
The 16,070 figure did not appear out of thin air. DHS had reported just last week that New York refused to honor 14,766 detainers. The newer total shows the ignored-detainer count has already moved higher.
An ICE detainer is a formal request asking local jails to hold a person a short time so federal officers can take custody for immigration proceedings. When localities decline those requests, people who would otherwise face removal can walk back out onto the street.
DHS Secretary Markwayne Mullin struck the same theme in comments to the New York Post this month. He cast sanctuary leaders as willing to free offenders while federal officers carry the risk.
"While sanctuary politicians continue to release dangerous criminals onto their streets, our brave law enforcement officers will continue to risk their lives to arrest these heinous criminals and make America safe again. Illegal aliens have no sanctuary in America,"
Mullin said. He repeated the charge that enforcement is moving ahead without help from Mamdani or Hochul.
Mamdani’s tenure has already drawn sharp national scrutiny on other fronts, including Israeli leaders’ condemnation of his rhetoric on Netanyahu. The DHS dispute now puts public safety and immigration cooperation in the same glare.
Federal officials have been tracking the pattern well beyond one state. In March, DHS reported that sanctuary states and cities across the country refused to honor an additional 18,000 detainers.
California offered an earlier warning. Early this year, ICE noted that the sanctuary state released 4,500 migrants convicted of murder, sexual assault, and child sex crimes without honoring detainers.
Those examples matter because they show the same mechanism at work: local non-cooperation, federal detainers ignored, and serious criminal histories left in the mix. New York’s latest totals sit inside that wider record, not outside it.
Readers following City Hall have also watched Mamdani face pressure over his silence at an October 7 vigil and related political fights. The detainer clash is a different arena, but it raises the same question of whether city and state leaders put enforcement first.
DHS did not publish a full offense-by-offense spreadsheet inside the Monday post. It did state a clear bottom line: 52,503 criminal charges and convictions were associated with the New York detainers that were not honored.
That is not a technicality. It is the agency’s measure of the criminal caseload connected to people local authorities declined to hold for ICE. For taxpayers and crime victims, the practical issue is simple. If the detainer is ignored, the federal handoff does not happen on schedule.
Mullin and DHS cast that gap as a choice by sanctuary politicians, not a paperwork accident. Their argument is that state and city leaders can help remove criminal illegal immigrants, or they can refuse and leave officers to chase the same offenders later.
Separate controversies around the mayor, including anger over how he handled Oct. 7 anniversary remarks, have already kept his judgment under a microscope. Immigration non-cooperation now adds a concrete enforcement scorecard to that scrutiny.
Neither Mamdani nor Hochul offered a response in the available reporting on the Monday post. DHS filled the silence with a direct accusation: New York’s top Democratic executives are not partners in enforcing immigration law.
Hochul, as governor, sets statewide tone on cooperation with federal authorities. Mamdani, as mayor, runs the nation’s largest city and its local justice machinery. When ICE files a detainer, those governments decide whether the hold is respected.
DHS says New York has decided against honoring thousands of them since January 20, 2025. The department’s public message is that the Trump Administration will not slow down because sanctuary officials refuse to assist.
Mamdani has also taken heat for an antisemitism plan that steered money toward an anti-Israel group, another reminder that his administration’s priorities are already a national fight. Public safety cooperation with ICE is now part of that same accountability test.
Federal officers still have to locate, arrest, and process people after a missed handoff. Mullin’s comments framed that work as dangerous and necessary, and he rejected the idea that illegal immigrants can hide behind local politics.
The policy contrast is stark. One side wants detainers honored so criminal cases lead to federal custody. The other side’s record, as DHS counts it, is thousands of refused requests and tens of thousands of linked charges and convictions.
New Yorkers living with the results did not invent those figures. DHS put them on the board, attached them to named leaders, and said enforcement will continue anyway.
Sanctuary talk is cheap until the detainer is ignored and the offender is back on the block, then the cost lands on the public, not on the politicians who looked away.
