Rousseff’s visit to Washington was her first since cancelling her trip last year following the disclosure of NSA spying. Leaks from Edward Snowden showed the U.S. spied on her personal communications as well as on Brazil’s state-run oil company, Petrobras. On Tuesday, Rousseff said she believes President Obama’s assurances that the spying has stopped.

Brazilian President Dilma Rousseff: “The change is particularly due to the fact that President Obama and the U.S. government have stated on several occasions that they would no longer engage in intrusive acts of spying on friendly countries. I believe President Obama. And furthermore, he told me that, you know, if he needed — should he ever need nonpublic information about Brazil, he would just pick up the phone and call me.”
