A federal judge temporarily blocked a Trump administration effort to freeze federal grants and potentially trillions of dollars in spending, but not before the Republican president’s declaration caused widespread tumult and confusion within Illinois government and among social service agencies,

Illinois Gov. JB Pritzker said President Donald Trump’s pause on federal funding is illegal and accused the administration of lying when it said programs that provide direct assistance like Medicaid would not be affected.

The funding freeze could affect trillions of dollars and cause widespread disruption in health care research, education programs and other initiatives. Grants that have been awarded but not spent are also halted.
