I think Mueller himself sees the handwriting on the wall. This week he asked for a pause and a delay in finishing up with Flynn. He surely sees the whole flimsy house of cards swaying and ready to tumble. S will HTF when Flynn, Manafort, et al, start suing. This whole thing will be a 3 Ring Circus.
I saw an analysis on a legal web site speculating the delay in sentencing was because the defendant was “singing” and being even more cooperative ... possibly to get Trump. Defendant’s attorneys had to agree to the delay which they did.
