The White House is accusing Republicans of “playing with fire” in their strategy to use Homeland Security funding to challenge President Obama’s executive action on immigration, after the deadly terrorist attack at a French satirical magazine.

Team Obama has long doubted that Republicans would unite behind an effective strategy to fight the president’s efforts to spare up to 5 million illegal immigrants from deportation. And now, the attack at the Charlie Hebdo office that left 12 people dead in Paris, they argue, offers clearer proof of the folly of such efforts.
