In a normal scandal story, the appropriate committee would grant immunity to Snowden, have him testify, then bring up Clapper, have him testify, and compare notes. Preferably publicly.

Here they bring in one side of the story for a secret Powerpoint presentation, no doubt with a high degree of spin to it, and publicly call Snowden a traitor. Then they complain that nobody shows up.

This isn't a bake sale or a dog and pony show, it's supposed to be the workings of the U.S. Senate. This sounds much more like an effort to CYA from the committee chair and NSA than it does an actual investigation or anything useful. Not going to make much progress continuing to operate in this fashion.

It IS interesting, however, that both sides here feel that, if only the other side knew more about what was actually going on, they would agree with them. But then the government insists on keeping it all secret. Meh.
