Immigration officials intervened at Barnes & Noble warehouse in Reno, Nevada today, as the bookseller released 50 workers that federal officials identified as undocumented immigrants.

The firings came one week after the bookseller announced that the U.S. Immigrations and Customs Enforcement Office had requested I-9 forms for all the employees at the Reno distribution center. According to Authorlink, a few employees have consulted with the ACLU about legal action.

Here's more from the article: "'Barnes & Noble has fully cooperated with Immigration authorities and has notified those employees identified by ICE. The Company is committed to observing all employment documentation standards for our employees,' said Mary Ellen Keating, corporate spokesperson for the company."
