German Newspaper Reports NSA Spied on Mexico's President

Der Spiegel reports Calderón's email was hacked

The National Security Agency hacked into the email of former Mexican President Felipe Calderón, according to a report in the German newspaper Der Spiegel.

The probe occurred amid years of U.S. eavesdropping on the Mexican government.

The spy agency reportedly wrote a top-secret report in May 2010, explaining that officials "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."
