Immigration and Customs Enforcement has been targeting so-called “sanctuary cities” with increased enforcement operations in an effort to pressure those jurisdictions to cooperate with federal immigration agents, a senior US immigration official with direct knowledge of ongoing ICE actions told CNN. A sanctuary city is a broad term applied to states, cities and/or counties that have policies in place designed to limit cooperation or involvement in the enforcement of federal immigration operations. More than 100 US jurisdictions — among them New York, Los Angeles and Chicago — identify as such. High-ranking ICE officials have discussed in internal meetings carrying out more raids on those locations, said the source. This week, a federal judge in Texas seems to have confirmed that tactic. US Magistrate Judge Andrew Austin revealed during an immigration hearing Monday that a mid-February raid in the Austin metro area was done in retaliation for a local sheriff’s recent decision to limit her department’s cooperation with ICE. “There’s been questions about whether Austin is being targeted. We had a briefing…. that we could expect a big operation, agents coming in from out of town. There was going to be a specific operation, and it was at least related to us in that meeting that it was a result of the sheriff’s new policy that this was going to happen,” Austin says in audio of the proceedings provided by the court.
