Sen. Warren seeks info from CoreCivic, GEO Group on federal compliance

• CoreCivic (CXW -0.5%) turns down and GEO Group (GEO +0.9%) pares earlier gains after Sen. Elizabeth Warren (D-MA), along with a group of other Democratic senators, sent letters to the two publicly traded operators of immigration detention centers requesting information about their compliance with federal immigration and detention standards.
• The letter follows a report from the the Department of Homeland Security Office of the Inspector General about unsafe conditions and mistreatment of immigrants at a number of privately run immigration detention centers, Warren's statement says.
• In their letters, the senators say that the companies lobbied to promote immigration policies that would boost their profits. The Trump administration reversed Obama-era policy to phase out the federal government's reliance on private prisons, the senators say.
