The Department of Homeland Security (DHS) said in a Sept. 20 statement that it warned California, Illinois, and New York state to cooperate with the federal government on deporting illegal immigrants.

The DHS said it was, via Immigration and Customs Enforcement (ICE), following up on letters sent to the three states’ attorneys general on Sept. 10 to confirm whether they would notify ICE when illegal immigrants are set to be released from jail or prison so they can be transferred into the agency’s custody.
