It took awhile for anyone even to contact Obama’s great uncle’s family (the uncle is still alive too).
The internet, like the MSM, thrives on rumor and misinformation. Research is so “old way”.

UPDATE: There are some anomalies in the story so far: according to the rumors, the Rainbow/Push conference was supposed to be held at Trinity United, yet schedules posted at Hillbuzz and elsewhere do not show the event as taking place at the church. Further, the schedule shows Michelle Obama as a “Special Guest,” not a speaker. Last, if it wasn’t at the church, why would the DVD have been on sale there? I remain highly skeptical that this story will amount to anything.
