Why so scared? - Part 2

Papadopolous was not freelancing and [...] others in the campaign were aware of his activities and on board with them.

[...]

We don’t know the identities yet of the unnamed campaign officials who received Papadopoulos’ updates. In the plea they’re called the “campaign supervisor” or the “high-ranking campaign official,” or “another high-ranking campaign official” (indicating at least two were directly in the loop).

There's a hook if I ever saw one. If you know you're the guy being referred to without being named, what would you do? And I'm looking at you, Jeff Sessions and Jared Kushner.  At least some of those guys will surely start singing for Mueller. (I'd almost bet on Sessions to squeal.) Especially considering this:

We know what Papadopoulos said to Trump campaign advisers, keeping them updated on his work and the conversations he was having with Russian officials. But, for the most part, we don’t know what they said back to him, but presumably Special Counsel Robert Mueller and his team do.

And when any one of them is called in on the record (and some already HAVE been) and lies because they didn't realize Mueller already had this info from Papadopoulos, they're automatically guilty of a crime - lying to the FBI. The guys on the lower rungs of the ladder might be as anxious as Papadopoulos to strike a plea deal by turning over even more evidence on the guys at the top.

The responses we have, thanks to this plea, are significant, and imply that Mueller has far more information about the role other campaign officials played and the views they had about working with the Russians.

Looks like this house of cards is ready to collapse.

...but hey, do what you want...you will anyway.
