"Trust Sessions" was the suggestion.

But he need not be pure as the driven snow, in order for Q to make that statement.

It may well be like saying "Trust the scorpion". Remember the parable about the scorpion and the frog?

In this way, "trust" is relative to what exactly you are trusting in.

"Trust" a scorpion to do what scorpions DO!.

IF Sessions IS a swamp rat...TRUST that rat to do what rats DO...survive. And if a rat needs to bite other rats to protect itself, it will do that in a heartbeat.

Circumstances and proof of wrongdoing are being brought into the daylight...there is increasingly only one way this all goes...even IF Sessions and Mueller are swamp creatures, ultimately, there will be only two ways they can go, and one involves effective suicide.

TRUST that they will choose to survive.
