Dick Russell's recent biography, The Real RFK Jr.: Trials of a Truth Warrior, contains two chapters on RFK Jr.'s quest for truth on the assassinations of his father and uncle.[1] Here is an excerpt from chapter 28:

He was approaching his midfifties when, in 2008, while preparing to give an environmental talk at the Franciscan Monastery in Niagara, New York, Bobby [RFK Jr.] found a copy of a just-published book "on my greenroom table, left as an anonymous gift for me." It was titled JFK and the Unspeakable: Why He Died and Why It Matters by Catholic theologian James W. Douglass. Bobby found the book "a fascinating and meticulous dissection of the circumstances surrounding the assassination." Bobby spent a lot of time examining Douglass's thorough footnotes. He noted "the extraordinary analysis implicated rogue CIA operatives connected to the Cuban project and its Mob cronies." Bobby was impressed enough to send the book to President Kennedy's speechwriter Ted Sorenson [Sorensen], who wrote him back in 2010: "It sat on a table for two weeks and then I picked it up. And once I started I couldn't put it down. And you know for so many years none of us who were close to Jack could handle ever looking at this stuff and all of the conspiracy books. Well, it seemed that nothing they had would stand up in court. All of us were, you know, 'it won't bring Jack back.' But I read this and it opened my eyes and it opened my mind and now I'm going to do something about it." Sorenson said he'd spoken to the author and planned to write a foreword for the paperback edition. "Thanks for getting the ball rolling," he wrote Bobby. However, Sorenson later told Douglass that his wife and daughter had persuaded him that his association with Jack had always been about the president's life and he should leave it at that. Sorenson died soon after that. Bobby himself "embarked on the painful project of reading the wider literature on the subject."[2]
