Chinese and Russian spying, has been published online. On Snowden, Alexander told Joye: "I suspect Russian intelligence are driving what he does. Understand as well that they're only going to let him do those things that benefit Russia, or stand to help improve Snowden's credibility".

On June 6, 2013, the day after Snowden's revelations, then-Director of National Intelligence James Clapper released a statement admitting the NSA collects telephony metadata on millions of Americans telephone calls. This metadata information included originating and terminating telephone number, telephone calling card number, IMEI number, time and duration of phone calls. Andy Greenberg of Forbes said that NSA officials, including Alexander, in the years 2012 and 2013 "publicly denied—often with carefully hedged words—participating in the kind of snooping on Americans that has
