Throughout the Trump Administration, the federal government has sought to undermine sanctuary policies by requiring that cities help ICE with immigration enforcement in order to receive certain federal grants from the DOJ. These policies have spurred a dozen lawsuits, almost all of which have ruled in favor of the cities challenging DOJ’s conditions. Recently, the Seventh Circuit has banned immigration enforcement conditions from all Byrne JAG Grants nationwide, although the Second Circuit has ruled (the only court to have done so) that DOJ is allowed to impose such requirements. This advisory explains more about the grant programs affected, the litigation, and what localities should know and do in the current environment.
