President Barack Obama is again urging the United States Congress to act on immigration. Obama made his latest appeal after the nation’s highest court failed to support his order protecting up to 5 million undocumented immigrants from deportation. The Supreme Court released that order last week. The court was split on the issue, with four members agreeing with the president and four others opposed. The ruling keeps in place a lower court decision that blocked the immigration order. The president called the Supreme Court ruling, “heartbreaking.” “I have pushed to the limits of my executive order,” he said. “We now have to have Congress act.” But congressional action seems unlikely before Obama leaves office in January. “We know there isn’t much left with this Congress,” said Norm Ornstein, a specialist on U.S. politics at the American Enterprise Institute. Orenstein said the ruling is bad news for the president because he had hoped to make immigration reform an important part of his legacy.
