Pope Leo XIV has urged labor union leaders from Chicago to advocate for immigrants and welcome minorities into their ranks. Leo weighed in as the Trump administration crackdown on immigrants intensifies in the pontiff's hometown. The audience on Thursday was scheduled before the deployment of National Guard troops to protect federal property in the Chicago area. The sites include a U.S. Immigration and Customs Enforcement building that has been the site of occasional clashes between protesters and federal agents. Chicago Cardinal Blase Cupich accompanied the labor leaders. Cupich said that Leo was well aware of the situation on the ground and has made clear that migrants and the poor must be treated in ways that respect their human dignity.
