Germany had something similar: a fact-finding committee tried to figure out what to do about NSA and our local spies spying on Germans local and abroad. Pro privacy parliamentarians wanted to rely heavily on Snowden docs, ruling party and anti-privacy required an in-person interview in Germany of Snowden to admit the docs as evidence.

Of course tthey didn't wwant to guarantee Snowdens freedom while here, so that interview never happened and the docs were ignored.

I bet that's going to be the NSAs play here too
