What was the purpose of the circus today?

Huber didn't show.

The evidence wasn't submitted.

My guess: Huber/Sessions/POTUS want the public to know about some of the investigations, but not the current state of those investigations. Huber doing a no show was a slap … congress has NO powers to prosecute. At the end, the whistle blowers punctuated that point.

Eat that, Nancy Pelosi.
