I can see Strzok being asked to come in for legal reasons connected to his criminal actions or those of others he had knowledge of; but not in the way the True Pundit article represents the situation.
This statement in the article, for example, it is absolutely stupid:
“Even top FBI officials are wondering how and why Strzok has been allowed to come back into FBI headquarters.”
I read on twitter - Eye the Spy (so take it for what it is worth) that Stroz is getting in with a visitor’s pass to talk with his “friends”. Perhaps this is on purpose so that Q et all can see who his “friends” are. Eye the Spy stated also that his security clearance was canceled.
