A lawsuit filed today by Republican attorneys general in nine states is asking a federal judge in Texas to declare the Deferred Action for Childhood Arrivals program unlawful. The lawsuit comes just two weeks after another federal court ordered the Trump administration to fully and immediately restore the program, known as DACA, in its original form. Since it was passed in 2012, DACA has granted protection from deportation and a work permit to at least 700,000 undocumented people who were brought to the United States as children.
