Well the NSA's activities have strong bipartisan support (at least as long as as the public doesn't have a great idea about what it does). No member of the intelligence committees has changed their position as a result of these recent disclosures. Both republicans and democrats have rushed to defend the NSA.

The problem isn't a rogue agency that doesn't have oversight. The problem is the law that allows the NSA to do just that. Take section 215 of the patriot act for example(it allows the government to obtain business records aka the verizon phone provision ); it is written in a way that makes it laughably easy to use for almost any use at all. The FBI doesn't even have to go to the FISA court but can choose any magistrate judge they want. The only restriction is "that such investigation of a United States person is not conducted solely upon the basis of activities protected by the first amendment to the Constitution." Wonderful......
