Immigrants across South Florida are bracing in anticipation of a wave of Immigration and Customs Enforcement raids ordered by the Trump administration. The big picture: President Trump has already acted on his promise to crack down on undocumented immigrants through large-scale deportation.

Among President Trump’s many immigration policies implemented since he took office, his plan for mass deportations has rattled migrant communities in Colorado and beyond.

Nearly 1,000 people were arrested by federal agencies in a blitz to enforce immigrations policies across the United States, according to multiple reports.

Targeted immigration enforcement operations by multiple agencies were launched in Chicago Sunday, with top Trump administration officials in the city to oversee the operation. Multiple sources told CBS News Chicago that those held by ICE Sunday have active warrants.

Immigration operations were taking place all over the country less than a week after President Trump was sworn in.
