clear now that the phone logging program that nsa uses, the big data mining program, did not in fact stop any terrorist attacks. the report makes that clear. your reaction? >> i think that's incorrect. i would cite the plans to set off a number of bombs in the new york city subways in 2009 on a pattern of the 2005 london attacks and i know that the information gathered by nsa under this program was a key factor in tipping us off as to what he was up to and he was stopped before i could do it. i think that's incorrect. intelligence is a lot of different indicators put together when done well to find what's going on and this program has contributed to that and i believe it's constitutional. i believe it should continue.
