House Minority Leader Nancy Pelosi, D-Calif., believes someone at the National Security Agency bears responsibility for the Edward Snowden leaks, saying Americans haven't heard the "whole story" about "culpability" for the leaks.

"How could this ever have happened?" Pelosi asked while discussing Snowden during her press briefing. "Who was accountable at the NSA for someone having access, with one person having access — not even a high-level person, that you might say, 'okay, somebody trusted that person' — how could one person have had that opportunity? I think that we have not heard that whole story and I keep asking that question. How did this happen?"

She continued, asking, "Who is responsible for that at the NSA and why aren't we hearing more about that? And I think there's culpability there, too."

The Prospect's George Packer recalled a Reuters report on Snowden's tactics while reviewing Glenn Greenwald's book on the revelations.

"Snowden borrowed logins and passwords from colleagues in order to gain access to more files," Packer wrote. "The article reported that 'A handful of agency [NSA] employees who gave their login details to Snowden were identified, questioned and removed from their assignments.' "
