The fugitive systems analyst spoke in video released Monday, filmed by The Guardian in June in Hong Kong before Snowden fled to avoid extradition to the U.S.
Snowden is believed to be stranded in a Moscow airport, trying to reach any country that has granted him asylum.
Snowden also said NSA chief Gen. Keith Alexander lied to Congress by saying the agency could not determine how many U.S. communications are gathered -- something Snowden says NSA auditing tool Boundless Informant does.
NSA officials had no immediate comment, but Alexander has said such data can only be analyzed when linked to foreign targets.
