Report: NSA Can Retrieve, Replay Foreign Calls
The Washington Post says the NSA has a system allowing it to record 100 percent of a foreign country's phone calls and listen back to them for up to a month.
The program has apparently been in operation for several years.
The NSA would not comment on the specifics but says it uses a variety of tools to identify threats.
