Summary: Do you know which U.S. president witnessed the beheading of his 11-year-old son? Or what president was the source of the colloquialism “OK”? This hour, in honor of the President’s Day holiday, author Kenneth C. Davis tells us about some of the least-known presidents of all-time from James Polk, the only speaker of the House of Representatives ever to be elected president, to William McKinley, the third of four presidents to die at the hands of an assassin. Davis is the best-selling author of “Don’t Know Much About The American Presidents.”
