At the beginning of the second Trump administration, 90% of the country’s 41,500 immigration detention beds were owned or operated by private prison companies. Now, after a year of congressional capitulation and the enormous increase in DHS funding, the Trump administration is proposing to vastly increase is immigration detention bedspace, mostly through private contractors and non-traditional prisons such as converted warehouses. Stopping these is a critical area of work, since fewer detention sites available helps to bottleneck ICE arrests, and cooperation from local governments and private corporations is necessary to permit and operate these facilities. Both are vulnerable to public pressure and present key opportunities for chapters to develop long-term campaigns in strategic collaboration with broad coalitions of migrant rights organizations.
