The editor of The Guardian says his newspaper has published just 1 percent of the material it received from former National Security Agency contractor Edward Snowden.

Alan Rusbridger is being questioned Monday by Parliament’s home affairs committee as part of a session on counter-terrorism.

The Guardian has published a series of stories based on Snowden’s leaks disclosing the scale of surveillance by spy agencies in the United States and Britain.

Rusbridger said the leak amounted to about 58,000 files.

Government and intelligence officials have said the leaks compromised British security and aided terrorists.

Rusbridger says The Guardian had “made very selective judgments” about what to publish and had not revealed any intelligence staffers’ names. He said: “We have published no names and we have lost control of no names.”
