C. David Heymann has written several biographies, including one of Bobby Kennedy, however, his latest book is sure to raise eyebrows with allegations such as Jackie Kennedy was spotted by a White House official in 1966 with RFK "straddling his lap, her arms around his neck."
At the time, Bobby Kennedy was married to his wife, Ethel, with whom he fathered 11 children.
Franklin Roosevelt Jr., President Kennedy's Undersecretary of Commerce, tells Heymann, "I suspect Bobby would've liked to dump Ethel and marry Jackie, but, of course, that wasn't possible."
