I believe McQueeg leaked the Brit dossier, didn’t he admit to it already?
I’m not sure, but Ms. Untermensch has made many wild claims (including accusing random people of being FSB agents), so it is best not to really get too caught up with her mad ravings. The article is accusing Sessions of “obstruction of justice”, which is nonsense even if what she claims is true—which we have on reason to believe, otherwise it would be reported in the MSM, not an Untermensch article.
