People participated in a protest in Chicago ahead of federal authorities kicking off a major immigration enforcement action on President Donald Trump's orders.

President Donald Trump's plan to dispatch National Guard troops and immigration agents into Chicago has put many Latino residents on edge, prompting some to carry their U.S. passports while giving others pause about openly celebrating the upcoming Mexican Independence Day.

But this year the typically joyful period coincides with Trump's threats to add Chicago to the list of other Democratic-led cities he has targeted for expanded federal enforcement.

His administration has said it will step up immigration enforcement in Chicago, as it did in Los Angeles, and would deploy National Guard troops. In addition to sending troops to Los Angeles in June, Trump deployed them last month in Washington, D.C., as part of his unprecedented law enforcement takeover of the nation’s capital.

Although details about the promised Chicago operation have been sparse, there's already widespread opposition extending into the suburbs. State and city leaders have said they plan to sue the Trump administration.
