Top Trump administration officials visited Chicago on Sunday to witness the start of ramped-up immigration enforcement in the nation’s third-largest city as federal agencies touted arrests around the country.

With two top Trump administration officials in Chicago, federal law enforcement began a “targeted” immigration blitz Sunday, according to a spokesman for U.S. Immigration and Customs Enforcement. The agency did not say how many arrests have taken place so far.

Public safety threats are the primary target right now, but the next phase of the immigration crackdown will be much less surgical and could begin "very soon," Tom Homan said.
