The National Security Agency hacked the email of former Mexican President Felipe Calderon, according to a report from Der Spiegel.
The report, which stems from documents leaked by Edward Snowden, alleges that a division of the NSA "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." Der Speigel also reports that the spying, which began in May 2010, also targeted other top officials in the Mexican government.
The report claims that some of the information retrieved in the surveillance program provided economic benefits to the U.S.

The report comes weeks after news that the NSA had access to current Mexican President Pena Nieto's emails, as well as Brazilian President Dilma Rousseff's.
Rousseff blasted the U.S.'s controversial surveillance program at the U.N. last month.
"Meddling in such a manner in the lives and affairs of other countries is a breach of international law and, as such, it is an affront to the principles that should otherwise govern relations among countries, especially among friendly nations," she said.
