There is no "news" here. In a usual hearing, there are adversarial interrogators who ask witnesses questions they weren't expecting, and they badger and argue with them.
Here, the illegally-formed committee is monolithic, all handpicked by Nancy Pelosi. There are no Republicans on it, just two ex-Republicans, one of whom is retiring to spend more time with his MSNBC, the other who will be running as an Independent with Democrat support against the Republican candidate.
They will present videotaped and edited "testimony." This is canned material that could just be released as a DVD to the press. Instead, it's being sold as a completely fake "news" event.
Where is the "news"? What's live here? The presenters introducing the videotaped and carefully edited interviews?
