With Chicago Police officers refusing to report their COVID-19 vaccination statuses, city streets soon could go unprotected. Illinois Gov. J.B. Pritzker is offering to call out the National Guard to keep order.

Chicago’s police union is planning to challenge Mayor Lori Lightfoot’s COVID-19 vaccination mandate and encouraging officers to ignore demands to report their vaccination status by Oct. 15. Only about 25% of police are vaccinated.
