In text released ahead of a lengthy interview to be broadcast on Sunday, ARD TV quoted Snowden saying the NSA does not limit its espionage to issues of national security and he cited German engineering firm, Siemens as one target.

“If there’s information at Siemens that’s beneficial to U.S. national interests — even if it doesn’t have anything to do with national security — then they’ll take that information nevertheless,” Snowden said, according to ARD, which recorded the interview in Russia where he has claimed asylum.

Snowden also told the German public broadcasting network he no longer has possession of any documents or information on NSA activities and has turned everything he had over to select journalists.
