Immigrants who were held at a private prison run by the GEO Group in Aurora, Colorado, have filed a landmark federal lawsuit, saying the company violated anti-trafficking law by forcing them to work for $1 a day under the threat of solitary confinement. This week, U.S. District Judge John Kane allowed the lawsuit to move forward. The immigrants say they spent hours cleaning toilets, mopping, and preparing meals. Attorneys say the lawsuit is the first of its kind.
