Administration officials on Tuesday postponed President Obama’s sweeping executive actions on immigration indefinitely, saying they had no choice but to comply with a federal judge’s last-minute order halting the programs. The judge’s ruling was a significant setback for the president, who had asserted broad authority to take executive actions in the face of congressional Republicans’ refusal to overhaul the immigration system. White House officials have defended the president’s actions as legal and proper even as his adversaries in Congress and the states have accused him of vastly exceeding the powers of his office.
