Has Senator Feinstein been Blackmailed?

Interesting interview of whistleblower Russ Tice, who claims that the NSA wiretapped Senator Diane Feinstein, chair of the Senate Intelligence Committee (which oversees the NSA). So what does it mean if the NSA is overseeing their overseers?

Feinstein to NSA chief, General Keith Alexander:  " I'd like more information on what kind of spying on Americans you're doing, and why you think it's important. "

Alexander to Feinstein:  "We just happen to have some very interesting phone conversations of yours as a sample of what kind of spying we do, and we think you'll understand why we think it is so important."

Feinstein (after briefly listening to the tapes):  "Oh, I see.  Well yes, I guess that is important.  What can I do to help your organization out?"

Alexander:  "Just tell everyone that what we are doing is necessary for national security and that Edward Snowden is a traitor."

Feinstein:  "Yes sir."
