Hear Obama put on a blackface accent and lie.
Obama told his audience that, because some folks had the courage to "march across a bridge" in Selma, Alabama, his mother, a white woman from Kansas, and his father, a black Muslim from Africa, took heart. It gave them the courage to get married and have a child.
The problem with that characterization is that Barack Obama, Jr. was born on August 4, 1961, while the first of three marches across that bridge in Selma didn't occur until March 7, 1965, at least five years after Obama's parents met.
