Deportation Research Clinic says information obtained through a Freedom of Information request showed that immigration officials detained at least 268 U.S. citizens between 2011 and June of 2017 — six of those in the Chicago area. Immigration officials said in a statement they don’t knowingly put U.S. citizens into removal proceedings.
