Greenwald: 'Amazing' that Clapper still employed

Guardian journalist Glenn Greenwald said Sunday it's "amazing" that Director of National Intelligence James Clapper still has a job and hasn't been prosecuted.

Clapper recently apologized to Sen. Ron Wyden (D-Ore.) for an "erroneous" statement given to Wyden over the scope of the National Security Agency's data mining programs, but Greenwald said on ABC's "This Week" he was surprised that's as far as it's gone given that Clapper was "caught red-handed lying to the American Congress."

"It's amazing that he not only hasn't been prosecuted but still has his job. And what that does is it lets national security officials continue to lie to the public," Greenwald said.

Greenwald said he plans to publish a story this week that reveals the scope of access that low-level NSA and government contractors have into phone and email communications.

"There are legal constrains for how you can spy on Americans," Greenwald said. "But these systems allow analysts to listen to whatever emails they want, whatever telephone calls, browsing history, Microsoft Word documents. It's an incredibly powerful and invasive tool."

Greenwald is mistaken, said top Senate Intelligence Republican Saxby Chambliss of Georgia, who said he visited with NSA officials last week and was assured otherwise.

"What I have been assured of is: There is no capability at NSA for anyone without a court order to listen to any telephone conversation or to monitor any email. In fact, we don't monitor emails," Chambliss said. "What the reporter gives is not correct. There are no emails that are monitored now."
