Long before Barack Obama was a president or politician, he was editor of the Harvard Law Review. In his capacity there, he once appeared on television to deliver a bit of knowledge for Black History Month.

In a 1991 TBS "Black History Minute" advertisement that has since resurfaced, Obama talks about Charles Hamilton Houston, the black lawyer best known for mentoring future Supreme Court Justice Thurgood Marshall and for his legal work combatting Jim Crow laws.

YouTube user Akaczynski, who provides the video below, looks to be compiling an assorted video record of past campaign ads and statements from prominent politicians, including Senate ads from both Obama and GOP presidential candidate Herman Cain.
