Where did this happen, under what circumstances and how did we get video?
This video is up on the site of www.gamaliel.org. It was taken at a Democracy Day Action in Washington DC in 2008. Also on their website they have a picture of Obama and under it it says,
“Barack H. Obama, former GAMALIEL ORGANIZER
of the United States!
Mr. President, THANK YOU for ORGANIZING HOPE for America and the World!”
Under that is a link for viewing his history with the organization.
