From a report: The U.S. Senate on Thursday passed a bill to renew the National Security Agency's warrantless internet surveillance program for six years and with minimal changes, overcoming objections from civil liberties advocates that it did too little to safeguard the privacy of Americans. From a report on CNET: The programs, known as Prism and Upstream, allow the NSA to collect online communications of foreigners outside the US. Prism collects these communications from internet services, and Upstream taps into the internet's infrastructure to capture information in transit. Some communications from Americans and others in the US are collected in the process. The vote Thursday renews the programs for six years. The House approved a bill renewing the programs last week. Former NSA contractor Edward Snowden first revealed the programs by leaking information about them to journalists in 2013. After the news coverage, the administration of President Barack Obama declassified much information about the programs.
