Hey silly little lib, I worked with the NSA for twenty years doing special ops in the Navy, and yes during the Clinton years we did the exact same thing, only we were looking for drug traffickers. INTERNATIONAL CALLS and EMAILS is the key (and yes that does include electronic transmissions between CONUS and OUTUS, not just OUTUS to OUTUS) The NSA has been doing this since day one, it's their job, it's their charter. ONLY the CIA is prohibited from spying on U.S. citizens, the other 12 agencies have dispensation to investigate within the U.S. as per their charters.
To all the idiot libs:
Catch a clue, bother to learn to read while your at college.
