Slowly — very, very slowly — attitudes toward NSA surveillance among Congressional representatives appear to be changing. A report from The Washington Post indicating that members of the Democratic leadership are open to reform measures warrants the question: How many total members of Congress currently support reform?

The first law is the Patriot Act, passed in October 2001 and revised in 2006 to allow the collection of phone records. The second is the Foreign Intelligence Surveillance Act, which was amended in 2008 to approve the government's surveillance of online activity.
