At 26 Federal Plaza, just blocks from Adams’ City Hall office, Trump’s Department of Homeland Security has been detaining migrants — including those with no history of violence — in conditions that surreptitious videos show are crowded and unsafe.

ICE agents last month arrested the most people in at least five years, but deportations are still lagging far behind what President Donald Trump has promised.

The speculation follows "border czar" Tom Homan’s promise to “flood the zone” – New York City – with U.S. Immigration and Customs Enforcement agents. The threat followed last weekend’s shooting of an off-duty Customs and Border Protection agent at Fort Washington Park in Upper Manhattan.
