I just today read in an Obama bio that he let his law license lapse in (maybe) 2003. I don’t know if this is relevant to having passed the bar or not.
A complaint has been filed against him with the Illinois State Bar

Thanks. I guess if he had a license, he must have been a member of the bar at some point. I just thought it was a little odd.
