Whitiker was sessions COS, he is part of the deep state. This report, when it comes out, will be enough for congress to impeach and remove Trump. That was the point of this whole thing and congress has been behind it from the beginning. They will be successful, but I believe there will be hell to pay.
.
There will be nothing criminal or significant in the report against Trump.
Mueller will be trying to get Trump to go easy on him. Mueller is the guy most in danger presently.

If what you say happens ( successfull coup i.e. impeachment of Trump), then I pray for a bloody civil war.
