The NSA agent accused of spilling the beans on America's most sensitive surveillance intelligence apparently has more secrets.
Edward Snowden reportedly has the "blueprint" documents of how our country's National Security Agency operates. If that information is made public, it could harm the United States.
"In order to take documents that prove that what he was saying was true, he had to take ones that included very sensitive detailed blueprints," Glenn Greenwald, journalist from The Guardian newspaper, said.
Greenwald is the columnist with the British newspaper who first reported on the intelligence leaks. He said Snowden has what he calls the "instruction manual for how the NSA is built."
"He is in possession of, literally, thousands of documents that contain very specific blueprints that would allow somebody who read them to know exactly how the NSA does what it does," Greenwald warned.
And perhaps more alarming is just how easy it was for Snowden to apparently get his hands on the treasure trove of data.
"Being able to inform people about the true severity of how much each NSA analyst has access to people's personal private communications with very little oversight, checks, or safeguards," he said.
Snowden emerged for the first time in weeks last Friday still in hiding in a Moscow airport. He is seeking Russian asylum until he can legally travel on to Latin America.
Russia said they'll grant his request but on condition that he stops the leaks.
Greenwald said the NSA agent has scores of documents on other surveillance programs that if released publicly would be very harmful to the United States.
"There are other domestic spying programs that have yet to be revealed, similar in nature to the ones we have revealed," he said.
The White House has urged Russia to send Snowden back to the United States to face felony charges.
"He is very resigned to the fact that things might go terribly wrong and he absolutely is at peace with that." Greenwald said.
He warned anyone trying to harm Snowden.
"It is not simply a matter of 'if he dies, things get released.' It is more nuanced than that," he explained.
"It's really a way of to just protect himself against extremely rogue behavior on the part of the United States, by which I mean violent actions toward him, designed to end his life." Greenwald said.
