President Donald Trump's chief policy adviser says the White House is exploring "all of our options" after a federal appeals court handed the administration a legal setback on Trump's executive order on immigration.

Stephen Miller tells NBC's "Meet the Press" that the White House could pursue "additional executive actions" — as Trump suggested on Friday — as well as judicial appeals.

Miller says the goal is to pursue "every single possible action to keep our country safe from terrorism."

He's also criticizing judges for taking "power for themselves that belong squarely in the hands" of the president.
