A report in the German magazine Der Spiegel based on Edward Snowden’s leaks and co-authored by Laura Poitras reveals the National Security Agency has been systemically spying on the Mexican government for years. A May 2010 report shows the NSA hacked into an email server used by then-President Felipe Calderón and his Cabinet members as part of an operation dubbed “Flatliquid.” Last month, current Mexican President Enrique Peña Nieto summoned the U.S. ambassador following reports the NSA had monitored his communications while he was still a candidate.
