The old article just had a few lines about this allegation, via an interview Greenwald gave to Brazilian media. This Spiegel article, co-written by Laura Poitras, treads a lot of newer and deeper stuff: > The National Security Agency (NSA) has a division for particularly difficult missions. Called "Tailored Access Operations" (TAO), this department devises special methods for special targets. > That category includes surveillance of neighboring Mexico, and in May 2010, the division reported its mission accomplished. A report classified as "top secret" said: "TAO successfully exploited a key mail server in the Mexican Presidencia domain within the Mexican Presidential network to gain first-ever access to President Felipe Calderon's public email account." > According to the NSA, this email domain was also used by cabinet members, and contained "diplomatic, economic and leadership communications which continue to provide insight into Mexico's political system and internal stability." The president's office, the NSA reported, was now "a lucrative source." > This operation, dubbed "Flatliquid," is described in a document leaked by whistleblower Edward Snowden, which SPIEGEL has now had the opportunity to analyze.
