The Washington Post Co. launched a new black culture site this morning called The Root, and Editor Henry Louis Gates Jr. has already made both Oprah Winfrey and Barbara Walters proud by making a celebrity cry. In a brief, unaired PBS interview posted to the site, Harvard professor Gates informs comedian Chis Rock that one of his ancestors enlisted as a Union soldier in the Civil War and was promoted to corporal. Rock is overcome and starts to cry, though he bounces back with a joke by the end of the video. Also, actor Don Cheadle isn't sure how to handle the news that his ancestors were enslaved by Native Americans instead of white people and Morgan Freeman gasps at a revelation about his white great-great grandfather. The main Washington Post site should be totally jealous of this content!
