Federal affirmation of assistance in the immigration law enforcement by States and political subdivisions of States

Reaffirming the existing inherent authority of States, law enforcement personnel of a State, or of a political subdivision of a State, have the inherent authority of a sovereign entity to investigate, identify, apprehend, arrest, detain, or transfer to Federal custody aliens in the United States (including the transportation of such aliens across State lines to detention centers), for the purposes of assisting in the enforcement of the immigration laws of the United States in the course of carrying out routine duties. This State authority has never been displaced or preempted by Congress.
