Files stolen by Eric Snowden reveal that the NSA spied on world leaders after being given their private numbers by a member of the Obama administration. The confidential memo shows that the NSA encouraged administration officials to share their Rolodexes in order to expand their base of spying on foreign leaders and their governments.
The document notes that one official turned over 200 numbers including the numbers of 35 world leaders. These were immediately sent out for monitoring by the NSA.
