The Trump administration is deploying law enforcement tactical units from the southern border as part of a supercharged arrest operation in sanctuary cities across the country, an escalation in the president’s battle against localities that refuse to participate in immigration enforcement.
The move reflects President Trump’s persistence in cracking down on so-called sanctuary cities, localities that have refused to cooperate in handing over immigrants targeted for deportation to federal authorities. It comes soon after the Justice Department and Department of Homeland Security announced a series of measures that will affect both American citizens and immigrants living in those places.
The specially trained officers are being sent to cities including Chicago and New York to boost the enforcement power of local Immigration and Customs Enforcement officers, according to two officials who are familiar with the secret operation. Additional agents are expected to be sent to San Francisco, Los Angeles, Atlanta, Houston, Boston, New Orleans, Detroit and Newark, N.J.
Lawrence Payne, a spokesman for Customs and Border Protection, confirmed that the agency was deploying 100 officers to work with ICE, which conducts arrests in the interior of the country, “in order to enhance the integrity of the immigration system, protect public safety, and strengthen our national security.”
The deployment of the teams will run from February through May, according to an email sent to C.B.P. personnel, which was read to The New York Times by one official familiar with the planning.
In sanctuary cities, the BORTAC agents will be asked to support interior officers in run-of-the-mill immigration arrests, the officials said. Their presence could spark new fear in immigrant communities that have been on high alert under the stepped-up deportation and detention policies adopted after Mr. Trump took office.
In a statement, ICE’s acting director, Matthew T. Albence, said the deployment comes in response to policies adopted by sanctuary cities, which have made it harder for immigration agents to do their jobs.
The Border Patrol squads will be charged with backing up ICE agents during deportation operations and standing by as a show of force, the officials said.
