Snopes response is weak. They just provide names and links to people who claim to have attended Columbia with Hussein. Did Snopes check them out as a real hoax-checker should? It doesn't look like it, especially the bulleted item on the Columbia 2008 press release on Zero. How would publishing something in '08 be proof he went there? Someone at Columbia claims him as an alumnus, why then doesn't Columbia prove it?
All very strange to me.
