Daniel Ellsberg speaks out on Edward Snowden

In my estimation, there has not been in American history a more important leak than Edward Snowden's release of NSA material – and that definitely includes the Pentagon Papers 40 years ago. The Pentagon Papers said that the Lyndon Baines Johnson Administration had systematically lied, not only to the public but also to Congress, about a subject of transcendent national interest and significance.

"Snowden's whistleblowing gives us the possibility to roll back a key part of what has amounted to an 'executive coup' against the US Constitution," said Daniel Ellsberg.
