It is time that the Michelle Obaba-Bernardine Dohn relatiobnship is investigated in depth. Their activity goes far beyond employment in a Chicago law firm, and it is quite possible that Dohrn mentored the young Michelle. While Obaba claims (mendaciously) that Ayers was just an acquaintance when he first entered politics, Michelle could hardly plead ignorance of the Ayers/Dohrn history in the Weather Underground.
From all appearances, Michelle was just a grievance monger at Sidley. I doubt anyone hardly spoke to her, much less confided in her.
