President Obama: US will probe reported NSA spying on Brazil, Mexico

President Barack Obama promised to look into a report the United States spied on the leaders of Brazil and Mexico, allegations that have caused tensions in Washington's ties to its two biggest Latin American partners.

President Obama met with presidents Dilma Rousseff of Brazil and Enrique Pena Nieto of Mexico during an international summit in Russia and discussed reports that the US National Security Agency snooped on their personal communications and phone calls. "I assured them that I take these allegations very seriously. I understand their concerns. I understand the concerns of the Mexican and Brazilian people; and that we will work with their teams to resolve what is a source of tension," President Obama said. President Rousseff, speaking earlier, indicated she was not fully satisfied with President Obama's assurances during their meeting. She said President Obama had agreed to provide a fuller explanation for the reported spying, and that she would decide whether or not to go ahead with a planned visit to the White House based in part on his response.
