FILE - In this Jan. 14, 2009 file photo, Argentina's President Cristina Fernandez, left, and her Chief of Cabinet Sergio Massa take a sip of water at the presidential residence in Buenos Aires, Argentina. Argentina’s leading opposition candidate for congress and mayor of Buenos Aires' Tigre district Sergio Massa, was robbed at his home on July 20, 2013, allegedly by Alcides Diaz Gorgonio, a navy intelligence agent who works in the security ministry under Sergio Berni, who answers to the president. He was detained after local police found Massa’s pen-drives in his house. Massa used to be Fernandez's Cabinet chief, but now he seems to be her biggest threat, leading an opposition slate that could end her control of congress. (AP Photo/Natacha Pisarenko, File) less
