The National Security Agency bugged nearly 30 Brazilian government phone numbers, according to the organization Wikileaks.
The organization published a top secret target list on Saturday that it said proves Brazilian President Dilma Rousseff was targeted and also her assistant, secretary, chief of staff, palace office and her phone on her presidential jet.
"The US targeted not only those closest to the President, but waged an economic espionage campaign against Brazil, spying on those responsible for managing Brazil's economy, including the head of its Central Bank," according to a press release from Wikileaks.
Other high-ranking finance ministers and a head at the Brazilian Central Bank are also on the list, according to Wikileaks.
Brazilian ambassadors to Germany, France, the European Union, the U.S. and Geneva were also targeted.
The U.S. has been flagged before for spying on allies such as Germany and France.
"Our publication today shows the U.S. has a long way to go to prove its dragnet surveillance on 'friendly' governments is over," said Wikileaks Founder Julian Assange in a statement.
The leaks were disclosed as the U.S. and Brazil are working on a climate deal that focuses on nuclear energy development as part of a way to address global warming.
