I think it's worth watching how the Republicans in the house 'questioned' Lewandowski, and how that hearing went in general. Because if she moves to a full inquiry, my understanding is that all these interviews will be opened up to Gym Jordan and McCarthy, who are basically Trump bumper-stickers with punchable faces.
Seems to me 3 things:
1. They're gathering the evidence, formally and legally, so it can be put together into a single case/document that is bullet-proof.
2. The GOP know full well how bad that evidence is, because to a shameless man they're attacking the process, not the crime.
3. Nancy Pelosi is good at politics. So as weird as it looks to me and you and many others, she's surrounded by smart people and is a smart person, who has lived this world for years.
