To said that it is unnecessary is naive at best. Those warrants work well if you know the call is going to occur in advance. Also to say they are illegal is being questioned by many great scholars on both sides. So for you to say it is illegal just shows your prejudice. This will probably die on the vine and if it does that just shows that it is legal and the Dems had nothing they could do. Instead of trying to constantly take this president down we should find ways to work together to better stop terrorist but that will probably not happen because of peoples selfishness. Oh well.
