This has been around since before the election.
Do you know that because you remember seeing it or because the video has a upload date consistent with it being out before the election? I ask because it seems like something created to debunk the video that I expect to see on Hannity this evening. I would imagine the date could be manipulated. It seems that everything can be.
Just going by the “posted on” date on the youtube page. And no, I don’t remember seeing it before the election.
All I did was Google “Obama Harvard” and I think it was one of the top results.
