Sounding more defiant NSA leaker Edward Snowden said what he called "the truth" cannot be stopped, even if he dies.
The declaration comes as Snowden made another charge: that in 2009 at two London summits U.S. spy teams helped wiretap foreign leaders at a pair of recent summits in Great Britain.
Then said the U.S. is hacking into Chinese computers.
"The more Edward Snowden lashes out the more he looks like somebody who's angry at the U.S. and wants to hurt the U.S. as opposed to being a whistle-blower trying to identify specific wrongdoing," said CNBC Chief Washington correspondent John Harwood.
On a web chat today, Snowden claimed what he's revealing are the NSA's "nakedly, aggressively criminal acts" not U.S. operations against legitimate military targets.
"The U.S.government is not going to be able to cover this up by jailing or murdering me." "Truth is coming, and it cannot be stopped," said Snowden.
As the revelations reverberated at today's summit, the President and NSA staffers worked to compile what they say is proof that the NSA programs have stopped terrorist attacks in the U.S.
