Chicago Mayor Brandon Johnson has joined members of the Mayors Migration Council at the United Nations in New York.

Johnson did not have public events scheduled Tuesday, although his press office confirmed that he would join mayors from around the globe at the U.N.

La Vonne Downey, professor of Public Administration and program director of Health Science Administration at Roosevelt University, said the mayor might have addressed the challenges Chicago faces as a sanctuary city.

“He might also want to talk about how we have or haven’t done a good job with being that. If he’s being forthcoming, he will talk about some of the issues with being that kind of sanctuary city in the sense that people who are already here don’t feel that they have the same access to services that migrant populations might have coming in, even if those are provided by nonprofits,” Downey said.
