The matter of what the intelligence advisors told the President regarding ISIS seems quite straight forward to anyone with a lick of common sense. Either, A., They told him and he didn't do anything or B., they didn't tell him.
If the answer is A. then the President's got some explaining to do. If the answer is B. then a bunch of people need to be relieved of their jobs. All the other talk and posturing is just that and amounts to nothing.
Personally, I'm inclined to believe the experts. They don't have a history of lying to me.
