He was “at” Columbia during the years in question. Only it’s not what you think. My guess is that he probably worked as a janitor- like Good Wil Hunting at M.I.T, only without the brains. Then, he probably dug some documents out of the garbage and did some forgeries, and conned his way into Harvard Law.
It would explain why he’s always talking about how the Republicans don’t know how to “clean up stuff”, and how they’re always talkin’ while somebody else is “holding the mop”.
That is actually a lot less believable than Obama's own version. Barack working for a living!
