My impression was that most of the Senators were scared to death of what she was saying. I realize that they have to keep any presentations on topic for the publicly advertised purpose of the hearing. They also have to beware of nuts dragging them into something that turns out to be hooey.
I might be projecting this, but the vibe I picked up from most of them was “we all know this corruption exists but we don’t talk about because then we’d be expected to do something, and that could prove fatal”. I suspect that the Senator who invited Breger to testify (Harris?) must not be part of the Club, and is either alrady shunned or will be getting The Talk real soon.
Your cynicism is most likely quite justified. I got quite the impression of things being swept rapid fire under the carpet. Most likely some of those folks are part of the scandal.
This is a situation where journalism could make the corruption impossible to hide but we no longer have independent journalism.
