Like I said, chances are this is nothing new, only difference is that we are hearing about it now where we never would have known it was going on before.
This is really a no-win situation for any president, sign the order and get heat for it, or don't sign it and hope that he doesn't have any direct involvement with a future terrorist attack, where surely the consequences would be much worse.
