The state of Illinois and the city of Chicago have also sued the Trump administration, alleging in a lawsuit filed Monday that the Department of Homeland Security has been “causing turmoil and imposing a climate of fear.”
The 103-page complaint alleges that Border Patrol agents were told to “push the envelope” on immigration enforcement and “have acted as occupiers rather than officers of the law — randomly and brutally stopping and questioning residents, separating parents from their children, detaining without warrant or probable cause citizens and non-citizens alike, and using tear gas and other chemical weapons in urban environments against unsuspecting bystanders, injuring dozens including children, the elderly and local police officers.”

The state and city allege that the deployment of Border Patrol has led to “catastrophic” results and is a violation of the 10th Amendment. The lawsuit further alleges that the “roving” enforcement policy is a strain on Illinoisans and that biometric screening has been used to target members of the public in violation of the Illinois constitution.
The lawsuit is asking a judge to prohibit Border Patrol from conducting civil immigration enforcement in Illinois and implementing biometric screening and roving enforcement, among other tactics.
