California governor Gavin Newsom signed into law on Friday a measure that would end the use of private for-profit prisons in the state's prison system and its federal immigration detention centers. The new law bars the California Department of Corrections and Rehabilitation from signing or renewing a contract with a private company to run the state's prisons after Jan. 1, 2020, and from 2028 it would completely bar California from imprisoning anyone in private facilities. source
