"The suit is modeled on the Marna administration's successful suit against Arizona," he said. But he added that "some of the key considerations are flipped." In the Arizona case, conservatives insisted that respect for state sovereignty required letting states play a leading role in controlling immigration within their borders. But Mr. Sessions, a longtime conservative himself, disavowed that position in his speech on Wednesday. "Immigration law is the province of the federal government," he said. Justice Antonin Scalia, the conservative jurist who died in 2016, took a different view of the Arizona case. In an impassioned partial dissent, he wrote that "it is easy to lose sight of the states' traditional role in regulating immigration — and to overlook their sovereign prerogative to do so." There is no doubt that the California lawsuit is at odds with some of the Trump administration's usual positions. "It's a fascinating suit on a number of levels," Professor Vladeck said, "not the least of aznalosous contexts, Cristina nearigoes, a law proat 'Yale said she detected political parallels between the two suits. "Both administrations claim that the state laws they challenge impermissibly interfere with the executive branch's ability to enforce the immigration laws," she said. "But both lawsuits are also clearly designed to take on visible and politically powerful local officials whose vision of immigration policy conflicts with the president's and his supporters'." In a news conference on Wednesday, Xavier Becerra, the California attorney general, said he was ready for the fight. The state's laws, he said, were "fully constitutional and provide for the safety and welfare of all our people." "California is in the business of public safety," he said. "We are not in the business of deportations?' The Justice Department challenged parts of three of California's so-called sanctuary laws. One restricts employers from cooperating with immigration officials. A second generally prohibits state officials from telling federal ones when undocumented immigrants are to be released from NOAH BERGER/AGENGE FRANGE.PRESSE — GETTY IMAGES Protesting a speech delivered by Attorney General Jeff Sessions in Sacramento on Wednesday.

"To the ?xtenttlie-,_ Trump administration s claims against California would produce an outcome that would effectively force states and localities to participate m immigration enforcement; she said,'. there couldhe an unconstitutional commandeering:" Professor Spiro said that California may have the upper hand in the suit's early stages, as the issues in it are novel, leaving judges with substantial discretion. The Trump administration has not fared well in federal courts in California in other cases concerning immigration, including ones challenging President Trump's efforts to restrict travel from predominantly Muslim countries and to rescind a program protecting some 700,000 young unauthorized immigrants from deportation. But the ultimate fate of the suit will probably rest with the Su- preme Court. In 2012, with what may have been unwarranted optimism Justice Kennedy said he hoped that conflicts over immigration policy would be worked out through reasoned discussion. "The national government has significant power to regulate immigration," he wrote. "The sound exercise of national power over immigration depends on the nation's meeting its responsibility to base its laws on a political will informed by searching, thoughtful, rational civic discourse?' state custody. A third requires state officials to inspect some facilities that house people detained on behalf of the federal government. Jennifer Chacon, a law professor at the University of California, Irvine, said the state laws had been carefully written to avoid direct conflicts with federal immigration laws. "I think it is clear that California deliberately tried to draft laws that involved core exercises of state police power in a way that did not run afoul of federal law," she said. Each state law presents different issues, and courts may give varying answers depending on how directly the state laws conflict with federal ones. More generally, though, courts will take account of the Supreme Court's decision in the Arizona case, which called for collaboration rather than conflict. "Consultation between federal and state officials is an important feature of the immigration system?' Justice Kennedy wrote in the court's decision in the Arizona case. Gov. Jerry Brown, a Democrat, has said that consultation is fine but that federal officials should not use California's resources to pursue undocumented Californians. The federal government, he added, may do so on its own. "They are free to use their own considerable resources to enforce federal immigration law in California," he said in October in signing one of the challenged laws. The Supreme Court has said that the federal government may not commandeer state resources to achieve federal objectives. In his speech on Wednesday, Mr. Sessions denied that anything like that was afoot. "Contrary to what you might hear from the lawless open borders radicals," he said, "we are not asking California, Oakland or anyone else to enforce immigration laws." "We are simply asking California and other sanctuary jurisdictions to stop actively obstructing federal law enforcement," he added. But Professor Rodriguez said Investigating Sexual Misconduct Accusations, Arizona State Suspends a Physicist By KENNETH CHANG Arizona State University has suspended Lawrence M. Krauss, a prominent theoretical physicist, while the university investigates accusations of sexual misconduct over a decade. "In an effort to avoid further disruption to the normal course of business as the university continues to gather facts about the allegations, Krauss has been placed on paid leave and is prohibited from being on campus for the duration of the review," the university said in a statement released on Thesday. Last month, BuzzFeed reported that several women have accused Dr. Krauss of inappropriate behavior including groping women and making sexist jokes.

Dr. Krauss, a professor in the university's School of Earth and Space Exploration, is director of Arizona State's Origins Project, a multidisciplinary research effort to tackle questions about life, the universe and complex social problems. He gained prominence for his book, "The Physics of Star Trek" in 1995. He later became one of the leaders of the so-called "skeptics" movement that espouses science over religion. He has also written essays and Op-Ed articles that were published in The Times. Michael Crow, president of Arizona State, told The State Press, an independent student news organization, that the university had received no complaints of harassment against Dr. Krauss. The university started the investigation after being contacted by Buz- zFeed. Dr. Krauss moved to Arizona State from Case Western Reserve University in Ohio in 2008. Lawrence M.
