Trump campaigned largely on the issue of immigration, promising to carry out mass deportations of roughly 11 million illegal immigrants currently in the U.S.

Trump’s administration has made it clear that the initial focus of ICE operations will be to target violent offenders who are in the country illegally.

Border czar” Tom Homan said the incoming administration is reconsidering plans for an immigration enforcement blitz in Chicago next week after preliminary details leaked.

Chicago's not off the table, but we're reconsidering when and how we do it because there was a leak,” Homan told Fox News.

Immigrants in Chicago and other U.S. cities have been preparing for immigration arrests since President-elect Donald Trump won the November election.

Trump's incoming "border czar" Tom Homan told ABC News late Saturday that they are now "reviewing any plans in Chicago because of the leak," adding that news reports may have potentially put officer safety at risk.

The fight over illegal immigration in Chicago has the potential to be among the fiercest in the country during the first weeks of Trump’s second term.

Since Trump’s victory in November, the American Business Immigration Coalition has held several dozen in-person and virtual training sessions with more than a thousand employers to prep for the sweeps.

Chicago Mayor Brandon Johnson reiterated his opposition to anticipated immigration reform policies when President-elect Trump returns to the White House this week.

The locations expected to be targeted by deportation teams from ICE include those with large populations of immigrants, one source said.

For millions in the U.S. illegally or with temporary legal status, the start of Donald Trump’s second term as president comes with a feeling their time in the U.S. may end soon.
