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.

Within hours of a federal lawsuit targeting Texas’ policy of letting its nearly 20,000 undocumented students qualify for lower public tuition rates, the 24-year-old law was no more.
