Looks to me like Wikipedia says he and Holder went to Columbia College, which is specifically differentiated from Columbia University. Nice try though.
What do you mean nice try? You are the one with the laughably stupid position. I went to Columbia College, and I can tell you that lots of people went to crappier schools then transferred to General Studies and go around claiming that they went to “Columbia”. That is a perfectly reasonable explanation as to why he doesn’t show up in Columbia College yearbooks.
So, I am stating the possibility that Obama is lying about which branch of the University he attended. You are claiming that he was in the CIA or something and made it all up.
