Arizona AG sues Trump administration over Surprise ICE detention warehouse. Attorney General Kris Mayes filed suit Friday against the Trump administration's plan to convert a 418,400-square-foot commercial warehouse in Surprise into an immigration detention center, arguing the site sits directly across from a hazardous chemical storage facility in violation of federal law. Mayes alleges the administration broke the National Environmental Policy Act (no public comment or environmental review), the Immigration and Nationality Act (facilities must be "appropriate" for housing people), and the Administrative Procedure Act. The originally planned 1,500-bed capacity has been reduced to 542, with 250 detainees expected by September. A federal judge in Maryland recently blocked a similar ICE warehouse project using nearly identical legal arguments.

Federal appeals court strikes down Trump's asylum ban. A panel of the D.C. Circuit Court of Appeals ruled Friday that President Trump's January 2025 executive order closing U.S. borders to asylum-seekers is "unlawful," finding it "cast aside federal laws affording individuals the right to apply and be considered for asylum." The ruling directly affects Arizona, a primary border-crossing corridor: monthly asylum encounters had dropped from more than 100,000 during peak 2023 to a few hundred after the order. The White House said the DOJ will seek further review.
