Separation of immigrant children
As part of the 2018 Trump administration's family separation policy, nearly 2,000 children of asylum-seeking families have been separated from their parents and placed in "detention centers." These centers have been described by commentators as "prisons" and "concentration camps". Former First Lady of the United States, Laura Bush, compared the images of the centers to internment camps. 16 out of 34 of the centers located in Texas had previously been cited by Texas officials for more than 150 health violations. Actor George Takei, who lived through the internment of Japanese Americans, described the separation of children as "worse" due to the separation of children from their parents.
