Last night, President Trump said he'd walk away from a planned summit with Kim if it's not fruitful. CIA Director Mike Pompeo met secretly with the North Korean leader over Easter.

Commissioner Richard Ross initially defended the action. But, today, he said he failed miserably in handling the situation.
