Gov. J.B. Pritzker, who has been delivering his daily news conferences from the Thompson Center in Chicago, said he is weighing public safety and the economy as he considers the effects of the stay-at-home restrictions, which have shuttered many businesses and kept people at home throughout the state. But with Illinois coming off a grim week in which about a third of the total cases confirmed since the outbreak’s start were tallied between April 12 and Saturday, the governor said he needs to consider the ramifications of softening restrictions too soon.
