The Trump administration asked the U.S. Supreme Court for an emergency stay that would let federal agents resume large-scale immigration raids across Los Angeles and much of Southern California. In a filing by Solicitor General D. John Sauer late Thursday, the Justice Department argued that a district judge’s injunction barring agents from stopping or detaining people based only on race, language, location or type of work “significantly interferes with federal enforcement efforts across a region that is larger and more populous than many countries.” The administration said roughly one in ten residents of the affected district—home to about 20 million people—are undocumented immigrants. U.S. District Judge Maame Ewusi-Mensah Frimpong issued the temporary restraining order in July after plaintiffs, including U.S. citizens, alleged that masked agents used racial profiling and lacked reasonable suspicion during what officials called the “largest mass deportation operation” in U.S. history. The Ninth Circuit declined on Aug. 1 to lift the order, prompting the emergency appeal. The government contends the injunction puts a “straitjacket” on Immigration and Customs Enforcement, which has been pressed by senior White House adviser Stephen Miller to reach a target of 3,000 arrests a day. Plaintiffs, backed by civil-rights groups, say the raids violate Fourth Amendment protections against unreasonable searches and seizures. The Supreme Court has not indicated when it will act on the request; the administration also asked for an interim administrative stay while the justices consider the petition.
