A for-profit immigrant family detention center in Karnes County, Texas, has banned migrant children held there from having access to crayons while their mothers meet with lawyers. Immigration authorities claim the ban is a response to children coloring on a table in the prison’s visiting area, which “caused damage to the contractor.” The facility is operated by the private prison company GEO Group, which saw its stock price jump after Donald Trump won the presidential election. Human rights advocates are calling for the Obama administration to cut ties with the private prison industry and end family detention before the close of his term.
