President Barack Obama gave a speech to a throng of reporters on Friday in an attempt to tamp down worry over recent revelations of comprehensive spying by the National Security Agency. Critics of the program call the surveillance a gross invasion of privacy and a violation of civil liberties.

The president delivered his remarks from Northern California, where he had traveled to showcase the implementation of the Affordable Care Act in that state. The media had other questions they wanted answered, however.

"When it comes to telephone calls," said Obama, "Nobody is listening to your telephone calls. That's not what this program is about. As was indicated, what the intelligence community is doing, they are looking at phone numbers, they are looking at durations of calls. They're not looking at people's names and they're not looking at content."
