The Justice Department has instructed attorneys to start using the phrase “illegal immigrants” instead of “undocumented immigrants” in reference to people who come into the country illegally, according to an email obtained by CNN.

“The word ‘undocumented’ is not based in U.S. code and should not be used to describe someone’s illegal presence in the country,” the email said, according to a CNN article published Tuesday.

The email also said “illegal alien” is the appropriate term for someone coming into the country illegally as defined in the U.S. Code.

This is another step implemented by the Trump administration in their fight against illegal immigration, which is becoming an even bigger issue ahead of the November midterm elections.

The president has deployed the national guard to assist border patrol at the southern border.

United States Border Patrol Chief Agent Rodolfo Karisch told the House Homeland Security subcommittee, “I think people seem to look at this as simply an immigration matter, which it’s not, you’re looking at still a war on terror that we’re fighting,” while also saying that Trump’s deployment has been helpful on Tuesday.
