Former NSA contractor Edward Snowden claims in a new interview that the U.S. agency is involved in industrial espionage.

German public television broadcaster ARD released a written statement before an interview airing Sunday night in which it quotes Snowden as saying that if German engineering company Siemens had information that would benefit the United States — but had nothing to do with national security needs — the National Security Agency would still use it.

ARD did not give any further context and it was not clear what exactly Snowden accused the NSA of doing with such information.

Snowden faces felony charges in the U.S. after revealing the NSA's mass surveillance program. He has temporary asylum in Russia.
