The new ICE tactics generated headlines in June when Brad Lander, the New York City comptroller and candidate for mayor, was arrested as he tried to prevent an immigrant from getting detained by agents at 26 Federal Plaza in Manhattan.

New York City officials and advocates say immigrants across the city are getting "unlawfully kidnapped" by ICE.

President Donald Trump’s border czar reiterated an explosive warning in a televised interview Tuesday that name-checked Portland, repeatedly pledging that immigration agents would be “doubling down, tripling down” on enforcement in sanctuary cities.

He was detained after a series of dramatic confrontations between federal law enforcement and Democrats opposing President Donald Trump's immigration policies.

The Federal Bureau of Prisons has been housing immigration detainees in jails and prisons following an interagency agreement in February. This month, more facilities are being added to the list.

That man is Mehran Makari Saheli, 56, who was arrested in St. Paul, Minnesota, on June 22. ICE said he was a convicted felon who was found guilty of being in possession of a firearm in Minneapolis, where he served 15 months in prison.

The complaint, filed in federal court in Albany, New York, alleges the law frustrates federal immigration enforcement at a venue - state courthouses - where authorities can safely make arrests.
