Mexico says it has won a pledge from President Obama to investigate the National Security Agency’s apparent spying on its government. Leaks from Edward Snowden reported by Der Spiegel suggest the NSA hacked the email accounts of then-President Felipe Calderón in 2010 and of current Mexican President Enrique Peña Nieto before he was elected. On Tuesday, Mexican Secretary of Foreign Affairs José Antonio Meade said Obama has promised an investigation and has assured Peña Nieto that he did not authorize the spying.
