President-elect Donald Trump has promised mass deportations. That could include thousands of people living in Philadelphia.

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.

The president-elect’s immigration advisers have warned Republicans that it will take time and money from Congress to carry out the mass deportation effort he has promised to execute immediately.

President-elect Donald Trump's administration will launch immigration sweeps in multiple U.S. cities almost as soon as he takes office on Monday with Chicago considered a likely first location, officials and rights advocates said.

Asked on Fox News if deportation raids would be launched in multiple cities, including Chicago, Homan said, "I wouldn’t categorize them as raids. There are going to be targeted enforcement operations.

President-elect Trump’s incoming border czar, Tom Homan, said Sunday that enforcement officials are “reconsidering” some of the details of the Chicago immigration operation after specifics were leaked to the press.
