UNDATED (NBC) -- -
Edward Snowden, the former National Security Agency contractor whose leaks revealed previously classified information about the extent of U.S. surveillance practices, made an argument for the end of mass data collection Thursday, but said not all spying is bad.
The comments emerged from a live chat held on the freesnowden.is website Thursday.
He also made allegations that the U.S. is engaged in economic spying.
"What I will say is, there is no question, that the U.S. is engaged in economic spying. If there is information at Siemens, that they think would be beneficial to the national interests, not the national security of the United States, they go after that information, and they'll take it," Snowden said.
Meantime, Attorney General Eric Holder says he would be willing to discuss a plea deal with Snowden, if and when he decides to return to the United States.
