FILE - In this May 2, 2013 file photo, Supreme Court Justice Sonia Sotomayor is seen at Metro State University in Denver. Massive government surveillance of Americans' phone and internet activity is drawing protests from civil liberties groups, but major legal obstacles stand in the way of any full-blown court hearing on the practice.
