The Trump administration has hit another court challenge to an immigration-related executive order. On Tuesday, a district court judge in California issued a preliminary injunction against last month’s order from the White House that so-called sanctuary cities—those localities that choose to harbor illegal immigrants and not report those aliens to immigration authorities—have certain federal grants withheld.

The Obama-appointed judge, William Orrick, said in his decision, “Federal funding that bears no meaningful relationship to immigration enforcement cannot be threatened merely because a jurisdiction chooses an immigration enforcement strategy of which the president disapproves.” For now, at least, the administration will be unable to carry through with its plans to withhold funds—at least, if and until the ruling is overturned.
