SAO PAULO - The Brazilian government says U.S. Vice President Joe Biden has telephoned President Dilma Rousseff in an effort to ease tensions created by the disclosure that the United States collected data on billions of telephone and email conversations in Latin America's biggest nation.
The Brazilian presidency's website says Rousseff and Biden spoke for 25 minutes on Friday night.
Communications Minister Helena Chagas told reporters that Biden called Rousseff to offer explanations and to "express his regret over the negative repercussions caused by the disclosures."
Chagas said Rousseff accepted Biden's invitation to send a delegation to Washington to receive "technical and political details" about the case.
Rousseff told Biden she wants the U.S. government to "change its security policies and practices," the communications minister said.
"The president told Biden that the privacy of Brazilian citizens and the country's sovereignty cannot be infringed in the name of security," she said.
