As the biggest defender of the NSA programs, it seems pretty hypocritical to complain about the CIA infiltrating her computer systems. Certainly, what the CIA did was illegal but, so are the NSA's programs. If she wants to complain about this, she should also be against the illegal NSA programs. I think this sums it up pretty well.

None of that should downplay what is actually happening. The CIA is spying on the people that oversee them. Both the NSA and CIA have greatly exceeded their authorizations. Neither of these organizations should have the power that they do and now it appears that they are willing to fight to keep it. The CIA is willing to spy on even their biggest supporter. This should not be acceptable under any condition. Even if you think that the surveillance is something that is needed, this should not be allowed. The intelligence agencies need to have oversight. Dianne Feinstein is on the oversight committee and as such needs to be free from this sort of activity. The Intelligence agencies need to be reigned in.
