The Department of Justice (DOJ) informed U.S. attorneys to use the term “illegal alien” when referring to an individual who entered the country illegally, according to CNN.

The news outlet said it obtained a DOJ-wide email that discourages attorneys from referring to immigrants in the country illegally as “undocumented.”

“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 DOJ indicated the memo was intended to ensure the department is “consistent in the way we draft our releases.”
