Update 8:04 a.m. Government contractor Booz Allen Hamilton says it's fired Edward Snowden, the employee who leaked details of a secret National Security Agency surveillance program.
The McLean, Va.-based firm says in a statement that it fired Snowden "for violations of the firm's code of ethics and firm policy." It said he had earned a salary of $122,000 a year.
Snowden had identified himself as the person who leaked top-secret information. He fled to Hong Kong in hopes of escaping criminal charges.
Previously: Pentagon Papers leaker Daniel Ellsberg calls the revelations by a government contractor on U.S. secret surveillance programs the most "significant disclosure" in the nation's history.
In 1971, Ellsberg passed the secret Defense Department study of U.S. involvement in Vietnam to The New York Times and other newspapers.
Ellsberg, 81, told The Associated Press Monday that the leaks by Edward Snowden, 29, to The Washington Post and The Guardian newspapers are more important than the Pentagon Papers as well as information given to the anti-secrecy website Wikileaks by U.S. Army intelligence analyst Bradley Manning.
Snowden, a former CIA employee who later worked as a contractor for the National Security Agency, told the newspapers about a government program that tracks American phone records and another one that tracks phone and Internet messages around the world.
"I was overjoyed that finally an official with high or a former official with high access, good knowledge of the abusive system that he was revealing was ready to tell the truth at whatever cost to his own future safety, or his career, ready to give up his career, risk even prison to inform the American people," Ellsberg said.
"What he was looking at and what he told us about was the form of behavior, the practice of policy that's blatantly unconstitutional. I respect his judgment of having withheld most of what he knows, as an information specialist, on the grounds that its secrecy is legitimate and that the benefit to the American people of knowing it would be outweighed by possible dangers. What he has chosen, on the other hand, to put out, again confirms very good judgment."
Ellsberg recently expressed support for Manning, who is now on trial. But Ellsberg said Manning didn't have access to information with the same "degree of significance" as the information released by Snowden.
"There has been no more significant disclosure in the history of our country. And I'll include the Pentagon Papers in that," Ellsberg said of Snowden's release.
"I fear for our rights. I fear for our democracy, and I think others should too. And I don't think, actually, that we are governed by people in Congress, the courts or the White House who have sufficient concern for the requirements of maintaining a democracy."
