Meanwhile, just before the long weekend, Illinois officials reported 81 outbreaks in schools — more than triple the number from the previous week. Some people, however, have taken issue with the fact that state health officials tightened the criteria of an outbreak from five related cases to two. Read more here from my colleague Karen Ann Cullotta and keep up with the latest on Chicago-area school cases using our tracker.

Chicago aldermen are up for their biggest raises in 15 years. Will any of them turn it down?

While many Chicagoans continue struggling to make ends meet amid the fallout from the COVID-19 pandemic, the city’s aldermen are currently facing their own struggle: whether to accept a nearly 5.5% pay raise for next year that will kick the highest-paid among them to a salary topping $130,000.
