Libs of TikTok found this going on at Chicago's famed O'Hare Airport, one of the country's largest and busiest:

Obviously, they ran out of space but the illegals kept coming, and are still coming. Rather than tell them to go pay for their own hotel rooms, the sanctuary city of Chicago keeps letting them in, and the result is inevitable, the space set for them in the airport (which was a really bad idea to start with) fills up, and as more come, they then spill over into the passenger waiting areas, setting up their tents and quasi villages in areas where passengers must wait for their flights.

That's a public space, and now the passengers who need that space, to either walk or sit down, can't use it, not easily, as they wait for their flights, or move about the vast airport to make their connections, dragging crying children, heavy suitcases, and carry-on bags, attempting to read the signs and overhead screens, while stepping over an illegals encampment. I'd be curious to see the crime statistics now that this is the state of traveling through the main airport of Chicago.

Seems the code inspectors who would normally stop this sort of thing as a fire-safety hazard or sanitation risk or zoning violation, have left the room. One set of laws for us, another set for them.
