Dan already did a fine job of explaining why the whole "Sessions/Russia" flap is a big nothingburger, so I won't rehash that here. What I will do is point out that the left seems to think this is chum in the political water. They've whipped themselves up in to a frenzy, fueled by anti-Trump hysteria and the hope that maybe - just maybe - they can finally get one of their conspiracy theories to stick.
Democrats, of course, are outraged. Why, they would never forget, ignore, or misrepresent a past meeting with a Russian diplomat! Most honest, upstanding, Dems have no reason to meet with Russian diplomats, because Ambassadors "call members of Foreign Rel Com." Isn't that right, Claire McCaskill?
