A sweeping plan by President Obama to protect immigrants from deportation might be in trouble. Arguments in the Supreme Court on Monday suggested justices were headed for a 4-4 split, reports the Los Angeles Times. If that proves true when the decision is announced in June, it's bad news for the administration because it means a lower-court ruling blocking the plan would remain in place, reports the Hill. Justice Anthony Kennedy sounded as if he thought that Obama overstepped his authority when he granted protection to about 4 million immigrants, mostly the parents of young US citizens. "That's a legislative, not an executive act," said Kennedy of the move. "It's as if the president is setting the policy and the Congress is executing it. That seems upside down."
