AUSTIN, Texas (AP) — The Justice Department on Wednesday sought to block a Texas law that for decades has given college students without legal residency in the U.S. access to reduced in-state tuition rates, the latest effort by the Trump administration to crack down on immigration into the country.

The Justice Department filed a lawsuit Wednesday alleging that the state of Texas is discriminating against out-of-state college students by allowing undocumented immigrants residing in Texas access to in-state tuition rates.
