Members of Congress expressed outrage at U.S. Immigration and Customs Enforcement for deceiving eight men who were recently deported to South Sudan, as revealed earlier this week in an investigation by The Intercept. Sen. Bernie Sanders, I-Vt., called the expulsions “abhorrent.”

Before the men boarded a plane in May, officials told them that they were being sent on a short trip from Texas to another ICE facility in Louisiana. Many hours later, the plane landed in Djibouti.
