'Legitimate questions' on US spying, Obama security advisor says

President Barack Obama’s national security adviser has conceded there are legitimate questions about US spying on its allies, as America sought to soothe Brazil’s concerns about far-reaching surveillance by the National Security Agency.

A White House meeting between Susan Rice and Brazil’s foreign minister, Luiz Alberto Figueiredo, constituted the latest attempt by the Obama administration to stem the damage to foreign relations inflicted by revelations by NSA leaker Edward Snowden. But it was not immediately clear whether that damage had been repaired.
