Sessions is the opposite of timid, apparently you didn’t know his history at all.
He’s just the quiet type who does not make announcements continuously or shout about what he’s up to. More dangerous to the bad guys that way.
Perhaps Sessions has a history of boldness against non Deep State types. But I've yet to see evidence that the same applies against Deep State corruption. Perhaps we could see that as time goes on. BUT, the recusal is indeed a timid move that doesn't give me confidence.
