I haven't seen any of the Wright video, but the description of a person with a responsible and rational approach, and a faultless demeanor, changing within a few days to a pompous, aggressive demagogue in front of other press members a few days later seems to be relevant to his motives. In other words, it doesn't seem likely that he had a plan to repay Obama, or harm him in any way, or it would have been more obvious at the start, no? Speculating, it seems more likely that he sees his duty to speak the truth as he sees it, and when antagonized, his frustration when faced with a dilemma –plain truth versus campaigning nuance – got the better of him?

Still hard to understand, though, what motivated him to set up that press schedule, especially with no prior notice to Obama. Selfishness seems most likely (but not rising to the level of deliberate self-aggrandizement, and not out of spite, either.) Just a guess. It really is a WTF event.
