::::I'm certain it is, or could easily be sourced that Barack Obama is African American, since thousands (at least) of articles call him the "first African American President"; that, plus the fact that the article does verify the ethnic origin of his families in reliable sources does verify his status as an African American. And if you think "Jewish" is an easy category, you've never tried to edit itwe've had hundreds of edit wars and users get blocked numerous times for fighting about who is or is not Jewish.  In any event, as for this article, your own personal knowledge is not sufficient, nothing from Gyan is ever acceptable for anything on Wikipedia, and we must have a clear source verifying ethnic identity.
