The new ordinance - a campaign promise from Lightfoot - eliminates those exceptions. It also forbids any "agent or agency" of Chicago from participating in "civil immigration enforcement operations" or assisting in the enforcement of federal immigration law. That prohibits police and city officials from stopping, arresting or detaining a person solely on their belief that the person did not enter the country legally. They also can not allow ICE agents access to a person who's being detained. Chicago police and city officials cannot use their time to respond to ICE inquiries or communicate with ICE regarding a person's custody status or contact information, per the new ordinance, nor can they set up a traffic perimeter or provide support to assist in an immigration enforcement operation.
