I think they will try, yes.
Maybe not…but they will be controlling any impeachment process and are controlling the Congressional investigative process. That will definitely be a big impact upon where the story goes and how it gets there.
Remember, impeachment is a political process, not a legal one.
What we are seeing now with the GOP stonewalling or slow walking any Congressional investigations into all of this is very similar to the old lawyer adage…Dont ask any question of a witness on the stand, if you don’t already know the answer. The GOP doesn’t know where this will end up, or how many people are going to be named and involved. Until they have a handle on that, they are going to continue to resist as long as they can.
But they are realizing that this story is going to continue and will drag people down regardless of their efforts. So right now, they are wanting to try and protect the VP. Which to me is a tell that they expect this story will ultimately take down Trump.
