WASHINGTON (AP) - President Barack Obama is urging Americans to "make some choices" in balancing privacy and security.
Obama is defending once-secret surveillance programs that sweep up an estimated 3 billion phone calls a day and amass Internet data from U.S. providers in an attempt to thwart terror attacks.
The president says it will be harder to detect threats against the U.S. now that the two top-secret tools to target terrorists have been so thoroughly publicized.
The National Security Agency has been collecting the phone records of hundreds of millions of Americans each day to learn whether terror suspects have been in contact with people in the U.S.
The NSA also has been gathering all Internet usage from major U.S. Internet providers in hopes of detecting suspicious behavior that begins overseas.
