Illinois could be at the center of conflicting agendas under a Trump presidency and Democrat-controlled state. With a Trump administration looking to end sanctuary city policies nationwide, Illinois could be ground zero in the fight.

The state also uses taxpayer funds to subsidize health care coverage for non-citizens, something that has cost taxpayers more than $1 billion. Costs are expected to continue.
