Cook County is staring down a budget hole of at least $260 million this year — and that’s under the “best-case scenario” in which the economy returns mostly to normal in June, officials said Friday.

The federal Coronavirus Aid, Relief, and Economic Security Act passed by Congress last month is likely to ease the county’s financial burden by covering some $100 million in expenses for items directly related to fighting Covid-19 in Cook County, but that does nothing to address the steep drop-off in taxes and other revenue the county is already tallying.
