Has the president overstepped? Texas and 16 other states are suing the federal government over Obama’s new legislation aimed at allowing five million erstwhile illegal immigrants to stay put. The states, which fear the move will “exacerbate the humanitarian crisis” along America’s southern border, claim that immigration reform is outside the president’s remit. The White House rejects this, saying Obama is well within his provided powers. But next week’s House vote on Homeland Security funding could force the administration to take a step back.
