RIO DE JANEIRO — Edward J. Snowden, the former US government contractor now living in Russia, said in comments published Tuesday that he was prepared to assist Brazilian investigations of US spying in Brazil. But he said he could not speak freely until a country grants him asylum, which he requested from Brazil months ago.
Snowden made his comments in an “open letter” published in a prominent Brazilian newspaper, Folha de São Paulo, in which he described the activities of the National Security Agency as potentially “the greatest human rights challenge of our time.”
His disclosures of NSA surveillance practices have shaken Washington’s relations with an array of countries. Brazil has reacted angrily over the spying, which included surveillance of President Dilma Rousseff. Full story for BostonGlobe.com subscribers.
