ICE City-Property Occupation — Mamdani Threatens Lawsuit Over ICE Use of NYC Parking Lots and Parks for Enforcement Staging

Nov 2-4: Mayor Mamdani sends formal letter to DHS/ICE demanding agency vacate NYC-owned parking lots and park spaces being used as staging grounds for immigration enforcement operations in Queens, the Bronx and Brooklyn; threatens legal action if the use does not stop. Documented NY first reported pattern of ICE using city property without lease or municipal authorization. City Hall framing: 'illegal commandeering' violating sanctuary-city posture and Fourth Amendment protections. ICE/DHS has not formally responded as of Nov 4. Escalates the Oct 8 Marble Hill ICE shooting backlash and comes 48 hours after Mamdani endorsed planned 'No Kings' NYC rally and labeled ICE a 'rogue agency'. First direct City-Hall-vs-federal-executive legal escalation of the Mamdani era.
