You really do need to brush up on your google skills.
It was revealed on 2007-01-28 by no less a libtard media organ than the New York Times:
As the president of the review, Mr. Obama once again walked a delicate line. He served on the board of the Black Law Students Association, often speaking passionately about the tempest of the week, but in a way that white classmates say made them feel reassured rather than defensive. He distanced himself from bombast; he did a mischievous impersonation of the Rev. Jesse Jackson when he came to speak on campus, recalled Franklin Amanat, now a federal prosecutor in Brooklyn. Mr. Obama’s boldest moment came at a rally for faculty diversity, where he compared Professor Bell to Rosa Parks.
Also, check out http://www.nytimes.com/packages/pdf/politics/2008OBAMA_LAW/Obama_CoursePk.pdf, the reading list from Professor Obama's course at the U of Chicago on Current Issues in Racism and the Law, Spring Term 1994, in which he assigns readings from Bell's works on Critical Race Theory, including the introduction to Faces at the Bottom of the Well (in addition to Vattel's Law of Nations, LOL!).
I don't see any what you think you see. That's hardly even a mention much less confirmation of an association.
