John Kerry defends NSA surveillance program

In this photo taken Aug. 9, 2013, Secretary of State John Kerry listens to translation as he meets with Russian Foreign and Defense ministers at the State Department in Washington, a sit-down tainted by the case of American National Security Agency leaker Edward Snowden, currently in Russia. This week on Kerry's first visit to South America as the Obama administration's chief diplomat, the disclosures by Snowden could chill talks on trade and energy, and even discussions about the Oct. 23 state dinner that President Barack Obama is hosting for Brazil's president, Dilma Rousseff.
