A 19-page audit of six New York City agencies said federal immigration authorities used aggressive and misleading tactics, prompting Mayor Zohran Mamdani to propose tighter sanctuary-law safeguards.
The sharpest finding was a surge in civil detainer requests: the NYPD received 3,672 in 2025, up from 99 a year earlier, while transferring no one to ICE.
The report said DHS staff at a shelter falsely claimed to be Fire Department officials, and federal agents visited shelters 10 times in April 2025—sometimes in plainclothes—seeking clients under the guise of child wellness checks.
It also described ICE agents entering a Brooklyn probation office by asking to use a bathroom before trying to inspect a sign-in book; staff stopped them and escorted them out.
Mamdani's office recommended limiting immigration-status details in reports, publicly tracking detainer requests, tightening shelter-access rules and requiring NYPD notification protocols, while the White House defended ICE enforcement.
