The U.S. government on Thursday sued New York City, seeking to block enforcement of several local laws its says are designed to impede its ability to enforce federal immigration laws.

In a complaint filed in Brooklyn federal court, the U.S. government said New York City’s “sanctuary provisions” are unconstitutional, and preempted by laws giving it authority to regulate immigration.

According to the Tenth Amendment, the federal government can’t force states to do the fed’s “regulating”. The states are not required to help you.
