A new report from the Congressional Research Service summarizes for Congress what is publicly known about the two National Security Agency surveillance programs that were disclosed by Edward Snowden and reported last month by The Guardian and The Washington Post.

“Since these programs were publicly disclosed over the course of two days in June, there has been confusion about what information is being collected and what authorities the NSA is acting under. This report clarifies the differences between the two programs and identifies potential issues that may help Members of Congress assess legislative proposals pertaining to NSA surveillance authorities.”

The CRS report does not present any new factual material concerning the surveillance programs. But it identifies some outstanding questions about them — the word “unclear” is used several times — and it formulates topics for congressional consideration. See NSA Surveillance Leaks: Background and Issues for Congress, July 2, 2013.
