Speaking at the National Sheriff’s Association 2020 Winter Legislative and Technology Conference in Washington, D.C., Barr said the Justice Department would immediately file multiple lawsuits against sanctuary jurisdictions for unconstitutionally interfering with federal immigration enforcement, and implement unprecedented national reviews of left-wing sanctuary governments and prosecutors.

“The department is filing a complaint against the State of New Jersey seeking declaratory and injunctive relief against its laws that forbid state and local law enforcement from sharing vital information about criminal aliens with DHS,” Barr said.

That was a reference to New Jersey Attorney General Law Enforcement Directive 2018-6, which the DOJ says illegally bars officials from sharing the immigration status and release dates of individuals in custody. It also requires New Jersey law enforcement to “promptly notify a detained individual, in writing and in a language the individual can understand” if Immigration and Customs Enforcement (ICE) files an immigration detainer request for the individual.
