In the United States, Department of Homeland Security Secretary Jeh Johnson has ordered DHS review its contracts with for-profit prison companies. This comes after the Justice Department told the Bureau of Prisons to end its use of private prisons earlier this month. DHS oversees a network of immigrant detention centers. About 34,000 immigrants are currently being held in for-profit detention centers. Human rights activists and some lawmakers celebrated the announcement. Arizona Congressmember Raúl Grijalva said, "This step is a tacit admission that the corporations who profit by locking up desperate adults and children undermine our decency as a nation." As with the Justice Department’s announcement two weeks ago, the DHS move caused the plunge of stocks for GEO Group and Corrections Corporations of America, two of the largest for-profit prison operators.
