State Rep. Susan Lontine, D-Denver, plans to introduce a bill removing the phrase “illegal alien” from Colorado law, The Denver Post reports.

Lontine has a large Latino population in her southwest Denver district and told The Post that “we shouldn’t be calling people illegal aliens. People aren’t illegal.”

The phrase occurs once in state statute, pertaining to contracting regulations. It is more commonly used in federal law.

The Illegal Immigration Reform and Immigrant Responsibility Act of 1996 alone contains 10 mentions of the phrase, including in a section hiring additional Justice Department prosecutors to pursue people who “bring into the United States or harbor illegal aliens.”

U.S. Citizenship and Immigration Services recently referred to “illegal aliens” in releasing the arrest histories for recipients of the Deferred Action for Childhood Arrivals program.

Even within the federal government, though, there is variation from agency to agency.

The Internal Revenue Service refers to “undocumented aliens” as those who enter “illegally without the proper authorization and documents, or who entered the United States legally and [have] since violated the terms of his or her visa or overstayed the time limit.”

And the U.S. Department of Education speaks of “immigrant children” in its explanation of how children are entitled to equal access to education regardless of immigration status.
