TRENTON, N.J. (AP):- The Trump administration is suing New Jersey over a state order that prohibits federal immigration agents from making arrests in nonpublic areas of state property, such as correctional facilities and courthouses.

The Justice Department lawsuit, filed Monday in federal court in Trenton, challenges Gov. Mikie Sherrill ’s Feb. 11 executive order, which also bars the use of state property as a staging or processing area for immigration enforcement.

Sherrill, a Democrat who took office Jan. 20, “insists on harboring criminal offenders from federal law enforcement,” the lawsuit said, accusing her of attempting to obstruct federal law enforcement and thwart President Donald Trump’s immigration crackdown.

Sherrill’s executive order “poses an intolerable obstacle” to immigration enforcement and “directly regulates and discriminates” against the federal government, said the lawsuit, which misspelled her name as “Sherill.”

Asked about the lawsuit Tuesday, Sherrill said: “What I think the federal government needs to be focused on right now, instead of attacking states like New Jersey working to keep people safe, is actually training their ICE agents.”

The state’s acting attorney general, Jennifer Davenport, said the Trump administration was “wasting its resources on a pointless legal challenge.” New Jersey will fight the lawsuit and “continue to ensure the safety of our state’s immigrant communities,” she said.

The lawsuit is the latest in the Trump administration’s fight against state and local level restrictions on immigration enforcement.

Last year, the Justice Department sued Minnesota and Colorado, as well as cities including New York, Chicago, Los Angeles and Denver over so-called sanctuary laws, which are aimed at prohibiting police from cooperating with immigration agents.

Last May, the Trump administration sued four New Jersey cities — Newark, Jersey City, Paterson and Hoboken — over such policies. That case is pending.
