Chicago Mayor Brandon Johnson said, starting Saturday, five facilities being used to house illegal immigrants would be reopened to the public, as “they are no longer necessary.”

The five parks used to shelter immigrants are a part of the city’s New Arrivals Mission in which Chicago, a sanctuary city, provides asylum to illegal immigrants who have been bused to the city from the Texas-Mexico border. On Saturday, efforts to transition immigrants out of five shelters will begin, allowing residents to resume using the Park District facilities popular for sports activities and summer camps.
