Brazil's president postponed a planned state visit to the United States over allegations that the National Security Agency has spied on her government.
"The President has said that he understands and regrets the concerns disclosures of alleged U.S. intelligence activities have generated in Brazil," said a statement from White House spokesman Jay Carney.
Brazilian officials objected after reports that the NSA has also used its capability to spy on other countries, including Brazil and Mexico. There are also allegations that the NSA hacked the computer network of Brazil's state-run oil company, Petrobras.
