Snowden offers to lend Brazil a hand

(CNN) - Former NSA contractor Edward Snowden traveled from Hawaii, to Hong Kong, to Russia. But the latest post card from Snowden is actually an open letter to the people of Brazil.

The man who got away with the "keys to the kingdom" of the intelligence community, according to one National Security Agency official, is now responding to what he says were requests by Brazil's government for a hand in their investigations of the United States' spying programs.

Documents previously leaked by Snowden have already accused the NSA of monitoring Brazil's president, advisers, and national oil company. Snowden says he is willing to help the country look into it all, but he adds one disclaimer that is being read by some as a hint: "Until a country grants permanent political asylum, the U.S. government will continue to interfere with my ability to speak."

Director of the American Civil Liberties Union's Speech, Privacy and Technology Project Ben Wizner discusses the implications.
