Steve Gilbert of Sweetness & Light highlights the awkward difference between Barack Obama's description of his post-Columbia work at a "consulting firm" in Dreams from my Father, and an account published by an source who worked at the same company Business International Corporation. [update: the source has been identified as Dan Armstrong, by no less than the New York Times, who cited him as an authority on Obama at the newsletter publisher. For the record, Business International was headed at the time by Orville Freeman, former Governor of Minnesota and Secretary of Agriculture for 8 years under JFK and LBJ. A career Democrat politician.]
As one somewhat familiar with the type of publishing this company did, the anonymous source's account rings very true to me, while Obama's rings false. But of course I cannot claim to be unbiased. Read Steve's account, his comments, and see for yourself.
