A federal judge has ruled the National Security Agency's bulk collection of millions of American's phone records is likely unconstitutional.
The data-mining program was revealed by NSA Leaker Edward Snowden.
Snowden issued a statement in response to the ruling, saying "Today, a secret program authorized by a secret court was, when exposed to the light of day, found to violate American's rights. It is the first of many."
But a Justice Department spokesman says "... we believe the program is constitutional as previous judges have found."
They say, the ruling is being studied.
