Protections for 660,000 Immigrants on Line at US Supreme Court Associated Press WASHINGTON - Protections for 660,000 immigrants are on the line at the Supreme Court. The justices are hearing arguments Tuesday on the Trump administration's bid to end the Deferred Action for Childhood Arrivals program that shields immigrants brought to the U.S. as children from deportation and allows them to work in the United States legally. The program was begun under President Barack Obama. The Trump administration announced in September 2017 that it would end DACA protections, but lower federal courts have stepped in to keep the program alive. Now it's up to the Supreme Court to say whether the way the administration has gone about trying to wind down DACA complies with federal law. A decision is expected by June 2020, amid the presidential election campaign. Some DACA recipients who are part of the lawsuit are expected to be in the courtroom for the arguments. People have been camping out in front of the court since the weekend for a chance to grab some of the few seats that are available to the general public. Chief Justice John Roberts has rejected a request for live or same-day audio of the arguments. The court will post the audio on its website . A second case being argued Tuesday tests whether the parents of a Mexican teenager who was killed by a U.S. border patrol agent in a shooting across the southern border in El Paso, Texas, can sue the agent in American courts. .
