Charlie Marder is a newly-minted congressman who stumbles upon a conspiracy that reaches all the way to the White House. Marder is the creation of Jake Tapper, who tells his story in his 1950s-era debut novel, “The Hellfire Club” (Little, Brown and Company). The host of CNN’s “The Lead with Jake Tapper” joins us to talk about fictionalizing themes and story lines that he reports on in his day job.
