Context
What happened: The Trump administration is suing the University of Delaware over a tuition policy that lets certain illegal immigrants pay in-state rates while out-of-state U.S. citizens pay more.
Key numbers: Resident tuition about $15,740 per year; nonresident about $42,470; difference $26,730; nonresident rate roughly 2.7 times resident.
Why it matters: DOJ cites 8 U.S.C. 1623(a) and 1621, calling the policy preempted twice over. An associate attorney general said DOJ will keep challenging policies giving preferential treatment to illegal aliens.
