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 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.

President-elect Donald Trump’s incoming border czar vows that the biggest city in the Midwest will be “ground zero” for mass deportations, and officials across the political spectrum in Chicago are bracing for a showdown.

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

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.

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

Federal immigration officers will target more than 300 people in the Chicago area with histories of violent crimes after President-elect Donald Trump takes office, an official said.

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

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

The Chicago city council on Wednesday blocked a proposal that would have allowed local law enforcement to assist Immigration and Customs Enforcement (ICE) to detain migrants with a criminal record.

Gov. J.B. Pritzker and Mayor Brandon Johnson have both said they are prepared to confront President-elect Donald Trump's policies head-on. But it is unclear how Trump will make good on his promises of retribution,
