I've been hearing a lot about the NSA's collection of phone records. What is it and how does it work?

The National Security Agency (NSA) collects data on millions of Americans’ phone calls, emails, texts, and other communications. It does this by tapping into the fiber optic cables that carry internet traffic and collecting information from the companies that own those cables. This includes information such as who you called, when you called them, and how long you talked.
