Chalk one up for Critical Race Theory. A groundbreaking new book utilizes DNA extracted from strands of Thomas Jefferson’s hair to provide definitive genetic proof that he fathered the children of Sally Hemings. The book, titled History by a Hair by Smithsonian scholar Richard Kurin, outlines the results of an advanced multi-year genetic study. The findings show that the odds of Jefferson not being the father of Hemings' sons, Madison and Eston, are less than 1 in 1,000.
