WASHINGTON - Congress may not be able to overhaul the immigration system, fix the broken tax code or even pass a budget. But it's telling the Library of Congress how to label immigrants living in the country illegally.

That's how conservative Republicans are responding to a move by the library to drop the term "illegal alien" in favor of "noncitizens" or "unauthorized immigration" for cataloging and search purposes. The move came in response to a petition from the American Library Association to change immigration-related search terms to make them less judgmental.

The library's move, announced in a three-page statement last month, was met with outrage from conservatives.

Tennessee GOP Rep. Diane Black said that the library is "caving to the whims of left-wing special interests."
