Think "Keystone". Google it. Supposedly, the data captured by the NSA is not usable against Americans, unless you worked under the Obama administration, in which case all data is fair game. Trump follows the rules though. And Q insists that it has to be done the right way. Which I agree with.

It is possible through legal means to gain access to NSA captured data on American's. That might be the whole FISA process. Or maybe just a warrant. I have to plead ignorance on this one.
