Joe Biden Was Outraged by Metadata Collection in 2006
In 2006, after a very similar story about NSA data collection broke, Senator Joe Biden expressed great concern about the government's collection of data on Americans' phone calls:
Biden: Harry, I don't have to listen to your phone calls to know what you're doing. If I know every single phone call you made; I'm able to determine every single person you talk to. I can get a pattern about your life that is very, very intrusive.
In a fuller clip of his remarks Biden did specifically express concern about lack of FISA court oversight of the monitoring. However that oversight seems to be of very limited value. And in any case, according to Glenn Greenwald, there was FISA court involvement during 2006.
