Snowden leak: NSA heavily involved in CIA's drone warfare

The latest leaked documents by National Security Agency whistleblower Edward Snowden show the extent the NSA has been involved with CIA counterterrorism activities, specifically drone strikes. In the past, the drone-strike program was presented as an exclusive initiative of the CIA, but the Snowden documents show that the program depends heavily on the NSA's ability to collect information from e-mails, phone calls and a myriad of other sources. In the meantime, Snowden's father Lon was able to visit the former government contractor in Russia this week, and arrived back in the US on Wednesday. RT's Ameera David has the NSA's response to the leaks about their involvement in drone warfare, as well as the advice Lon Snowden gave his son.
