Brazil’s President Dilma Rousseff toured the Silicon Valley and NASA facilities on the last day of her official visit to the United States and also met with the president of Google. Her visit included positive exchanges with President Barack Obama including agreements on renewable energy goals and food security. Although Obama did not issue a formal apology for NSA spying on Rousseff, he assured her that should he ever need non-public information in the future, he would just pick up the phone and ask her. teleSUR
