The city of Chicago is working with the CTA to provide warming buses during overnight hours at 16 police district locations where migrants are being housed and at the landing location where migrants are first being dropped off when they arrive in Chicago, Mayor Brandon Johnson announced on Tuesday. The buses will be available from 8 p.m. to 8 a.m. while city officials work to expand the number of buses available for warming stations. "With colder weather upon us, we are at an increasingly critical point in this humanitarian endeavor," Johnson's administration said in the news release. "To protect new arrivals and unhoused Chicagoans from falling temperatures, the City is collaborating with external partners, volunteers, and mutual aid groups to provide blankets, coats, and other much-needed items."
