Business leaders and employers across the United States, including in Chicago, are raising alarms over immigration raids as President-elect Donald Trump prepares to implement his mass deportation policy.

A bustling shopping district in Chicago known as the “Mexico of the Midwest” has seen foot traffic plummet by 50% — as residents say they fear the immigration raids promised by President Trump. The sidewalks were empty and some businesses were closed along a two-mile stretch of shops and restaurants on 26th Street in Chicago’s Little Village — the Windy City’s second-busiest retail corridor — as Trump was sworn into office Monday.
