It being Holy Week and all, Sean Hannity’s show on Fox News last night featured an interview with the author of “Killing Jesus.” The show’s host and the “Killing Jesus” author discussed the parallels between Jesus’s time and contemporary times, particularly the existence of corrupt religious leaders and corrupt politicians, myths surrounding the killing of Jesus and a conspiracy among a “small group of corrupt religious leaders [who] had been hunting for him almost from the beginning.”

At the end of the segment, Hannity offers a nice plug for the book.

Adjacent Fox News host and “Killing Jesus” author Bill O’Reilly ought to be pleased with that promotion, right?

Wrong. Hannity was plugging another “Killing Jesus” book, the one by author Stephen Mansfield, with the full title “Killing Jesus: The Unknown Conspiracy Behind the World’s Most Famous Execution.” It’s due out in May. Mansfield is a prolific author on topics of religion who has turned in several appearances with Hannity to discuss faith and politics. For a book on radio host Paul Harvey co-authored by Mansfield and David A. Holland, Hannity wrote the foreword.

All of which means that Hannity appears to be a bit tighter with “Killing Jesus” author Mansfield than with “Killing Jesus” author O’Reilly. The recent biography of Fox News chief Roger Ailes by author Zev Chafets reports that Hannity and O’Reilly don’t speak to each other. Also: Within Fox News, reports Chafets, there’s “widespread criticism of [O’Reilly’s] relentless promotion of his bestselling books and public appearances.”

Killing Jesus: A History,” by O’Reilly and Martin Dugard, is due out in September. Given the hype it has already picked up, it won’t need a “Hannity” plug.
