U.S. President Donald Trump began a wide-ranging immigration crackdown when he took office on January 20, aiming to reduce illegal crossings at the U.S.-Mexico border and deport record numbers of immigrants who lack legal status.

As U.S. President Donald Trump pledges to deport “millions and millions” of “criminal aliens,” thousands of federal law enforcement officials from multiple agencies are being enlisted to take on new work as immigration enforcers, pulling crime-fighting resources away on other areas − from drug trafficking and terrorism to sexual abuse and fraud.

ABC News’ Alex Perez reports from Chicago on how the Trump administration’s immigration crackdowns are causing mixed emotions, spurring fear in so many while others want to see resources reallocated.
