Aug. 28 (UPI) -- The Justice Department is suing four more states over offering in-state tuition benefits to qualifying undocumented students, for a total of 21 lawsuits filed against so-called Dream Acts amid the Trump administration's anti-immigration push.

The lawsuits against Arizona, New Mexico, Oregon and Washington -- all Democratic-led -- were individually filed Thursday, alleging their laws providing undocumented students with in-state tuition and financial assistance unconstitutionally discriminate against out-of-state U.S. citizens to whom such benefits are not offered.

"By granting illegal aliens in-state tuition, Washington, Oregon, New Mexico and Arizona are pushing citizens to the side and ignoring federal law. No more," Associate Attorney General Stanley Woodward Jr. said in a statement.

"Our efforts will not cease until President Trump's promise is fulfilled: illegal aliens will not receive benefits denied to American citizens."
